GENERAL HAZARD WARNING

SE405 Manual Rev. 1.2 P/N:974-9885 Page 3SE405 Manual Rev. 1.2 P/N:974-9885 Page 3

READ THIS

WARNING

FIRST !

The heater is designed and approved for use as a construction heater

under ANSI Z83.7a-2007. The primary purpose of construction heat-

ers is to provide temporary heating of buildings under construction,

alteration, or repair and to provide temporary emergency heat. Prop-

erly used, the heater provides safe economical heating. Products of

combustion are vented into the area being heated.

The heater is not designed as an Unvented Gas Fired Room Heater

under ANSI-Z21.11.2 and should not be used in the home.

ANSI A119.2(NFPA 501C)-1987 Recreational Vehicle Standard

prohibits the installation or storage of LP-Gas containers even

temporarily inside any recreational vehicle. The standard also prohib-

its the use of Unvented Heaters in such vehicles.

Installation must comply with local codes, or in the absence of

local codes, with the National Fuel Gas Code ANSI Z223.1/NFPA

54 and the Standard for the Storage and Handling of Liquified

Petroleum Gases ANSI/NFPA 58.

We cannot anticipate every use which may be made for our heaters.

CHECK WITH YOUR LOCAL FIRE SAFETY AUTHORITY IF YOU

HAVE QUESTIONS ABOUT LOCAL REGULATIONS.

Other standards govern the use of fuel gases and heat producing

products in specific applications. Your local authority can advise you

about these.

FOR YOUR SAFETY

DO NOT USE THIS HEATER IN A SPACE WHERE

GASOLINE OR OTHER LIQUIDS HAVING

FLAMMABLE VAPOURS ARE STORED OR USED.

INSTALLATION

The Sure Flame Model SE405 Construction Heater is a direct fired gas heater

intended to be used primarily for the temporary heating of buildings under

construction, alteration, or repair. Since all the products of combustion are

released into the area being heated, it is imperative that adequate ventilation

is provided.

1 Install the heater in a horizontal position at least 10 feet (3m) from any

LP-gas container. Allow the following clearances from any combustible

materials:

Front Outlet: 12 feet (3.7 m) Sides: 2 feet (0.6 m)

Intake: 2 feet (0.6 m) Top: 5 feet (1.5 m)

Front Outlet must not be directed at any LP-gas container within 20 feet

(6 m).

The heater is designed for use with up to 25 feet of 18” ductwork.

Ductwork must be able to handle temperatures of up to 300°F. Only

duckwork supplied by the manufacture shall be use with this heater.

Also make sure that no flammable vapours are present in the space where

the heater is being used.

2 When connecting the heater to a natural gas or propane supply line ensure

that the pressure at the heater inlet is within the specified range. Excessive

pressure (over 1/2" psi) will damage the controls and void the warranty.

3 Visually inspect the hose assembly and ensure that it is protected from

traffic, building materials, and contact with hot surfaces. If it is evident that

there is excessive abrasion or wear, or the hose is cut, it must be replaced.

4 After installation, check the hose assembly for gas leaks by applying a

water and soap solution to each connection.

5 Connect the heater to an adequate 120 volt electrical supply as specified

on the rating plate. For protection against shock hazard the supply cord

must be plugged directly into a properly grounded three-prong receptacle.

Note: Low Voltage (long extension cord or too many items on circuit) will

shorten motor life.

INSTALLATION USING A

PROPANE SUPPLY TANK

1 When installing the heater for use with propane gas, set the gas selector

valve to “Propane” and lock in position.

2 Arrange the propane supply system to provide for vapour withdrawal from

the operating container. Supplying liquid propane to the heater is danger-

ous and will damage the components. Another regulator must be

installed on the heater to reduce the pressure from this regulator to a

maximum inlet pressure of 1/2 psi.

3 Ensure that for the surrounding temperature the size and capacity of the

propane supply container is adequate to provide the rated Btu/h input to

the heater.

4 Turn off the propane supply valve at the container when the heater is not

in use.

5 The installation must conform with local codes, or in the absence of local

codes, with the Standard for the Storage and Handling of Liquedied

Petroleum Gases, ANSI/NFPA 58.

6 When the heater is to be stored indoors the propane container must be

disconnected from the heater and the container moved away and stored

in accordance with the above national standards.

INSTALLATION FOR

NATURAL GAS APPLICATIONS

1 When installing the heater for use with natural gas, set the gas selector

valve to the “Natural” position.

2 A regulator must be installed on the heater to ensure that the pressure to

the heater does not exceed 1/2 psi inlet pressure.

3 The installation of this heater to a natural gas supply must conform with

all applicable local codes, or in the absence of local codes, with the

National Fuel Gas Code ANSI Z223.1/NFPA 54.

HEATER OPERATING INSTRUCTIONS

1) Set GAS SELECTOR VALVE to gas being used. The conversion shall

only be done by the owner or lessor of the equipment.

NOTE: When using Propane Gas the SELECTOR VALVE must be locked

in position.

2) Ensure valve is in the "ON" position.

3) Connect Power - 120 volt supply. Open gas supply.

4) Set switch to "HEAT" mode.

5) Push "START" button.

6) If equipped with a thermostat, set thermostat to desired temperature.

To stop, push the "STOP" button and turn gas off. Fan will continue

operating for 60 seconds.

The appliance area should be kept clear and free from combustible materials,

gasoline, and other flammable vapours and liquids.

Ensure that the flow of supply air and combustion gases is not obstructed.

The installation and operation of the heater shall comply with the code

requirements specified by the authorities having jurisdiction.

THE INSTALLATION AND MAINTENANCE OF THE

HEATER MUST BE ACCOMPLISHED BY A

QUALIFIED SERVICE PERSON.

FAN OPERATING INSTRUCTIONS

1) Set switch to "FAN" mode.

2) Push "START" button.

To stop push the "STOP" button.

PREVENTIVE MAINTENANCE

Sure Flame construction heaters are built to withstand the rigours of operating

on construction sites, in mining applications, and in a multitude of other

locations where heaters are used. To maintain the reliable performance

required it is necessary to do a certain amount of regular maintenance.

PERIODIC MAINTENANCE:

Weekly:

Gas Hose Check for cracks or damaged connectors

Obstruction of Air flow Clean & remove debris

Monthly:

Cords & Connectors Check for cracks, exposed wires & dirt in

electrical connectors. Clean with water and

dry out before connecting power.

Physical Integrity Check for damage to body, louvers and

inlet screens that may impact combustion

quality.

End of season:

Manifold Pressure Check for nominal pressure specified in

specification label. Adjust regulator

pressure if necessary.

Fan Blade Remove dirt buildup. Replace damaged or

unbalanced blades.

Strainer Inspect and clean if necessary.

Combustion Chamber &

Flame Rod

Remove nose cone and inspect inside for

integrity. Remove accumulated carbon

deposits with a wire brush. Clean flame

rod with solvent or emery cloth. Inspect

insulator for cracks. Check flame rod tip for

1/8” gap to ground. Install nose cone.

Gas leaks Using soapy water or gas leak detector

check all gas connections for leaks

Air Tubes Verify that air tubes are not blocked and

that they are securely attached with a 1/8”

gap from the combustion chamber wall.

Wiring &

Drain holes

Check the electrical box for loose or

overheated wires and connectors. Using a

dry cloth or compressed air clean bottom

drain holes if necessary. Check for

integrity of cover seal.
