  Propane/LP gas is a fuel gas.

Fuel gases are odorless. An odor-making agent

is added to fuel gases. The odor helps you detect

a fuel gas leak. However, the odor added to fuel

gas can fade. Fuel gas may be present even though

no odor exists.

Make certain you read and understand all warn-

ings. Keep this manual for reference. It is your

guide to safe and proper operation of this heater.

5. Inspect the hose before each use of the heater.

If it is evident there is excessive abrasion or

wear or the hose is cut, it must be replaced

prior to the heater being put into operation.

Use replacement hose assembly kit #LPA3090

(see Accessories, page 17).

6. Use only propane gas set up for vapor with-

drawal.

7. This heater shall not be installed in a bedroom

or bathroom.

8. This heater needs fresh, outside air ventilation

to run properly. This heater has an Oxygen

Depletion Sensing (ODS) safety shutoff sys-

tem. The ODS shuts down the heater if not

enough fresh air is available. You must provide

a minimum 10 square inches of ventilation air

for adequate combustion.

9. If heater shuts off, do not relight until you

provide fresh, outside air. If heater keeps

shutting off, have it serviced.

10. Keep all air openings in front and bottom of

heater clear and free of debris. This will insure

enough air for proper combustion.

11. Do not use heater if any part has been under

water. Immediately call a qualied service

technician to inspect the room heater and to

replace any part of the control system and any

gas control which has been under water.

12. Turn off and let cool before servicing. Only

a qualied service person should service and

repair heater.

13. Operating heater above elevations of 4,500

feet could cause pilot outage.

14. Turn off propane/LP supply when not in use.

15. Check heater for damage before each use. Do

not use a damaged heater.

16. Do not alter heater. Keep heater in its original

state.

17. Do not use heater if altered.

18. This heater can only be used in a recreational

or commercial enclosure with a window or

roof vent. This heater is not for outdoor use.

19. Before using the heater provide adequate

ventilation. An area of 10 square inches of

opening of a window or roof vent is needed

for adequate combustion and ventilation air.

PRODUCT

IDENTIFICATION

PROPANE/LP SUPPLY

Propane/LP gas and propane/LP tank(s) are to be

furnished by the user. The propane/LP cylinder

to be used must be constructed and marked in

accordance with the specications for the pro-

pane/LP gas cylinders of the U.S. Department of

Transportation (DOT).

Use this heater only with a propane/LP vapor

withdrawal supply system. See Chapter 5 of the

Standard for Storage and Handling of Liqueed

Petroleum Gas, ANSI/NFPA 58 and/or CAN/CGA

B149.2. Your local library or re department will

have this booklet.

The amount of propane/LP gas ready for use from

propane/LP tanks varies. Two factors decide this

amount:

1. The amount of propane/LP gas in tank(s)

2. The temperature of tank(s)

This heater is designed for use with a 20 or 40

pound rellable propane/LP cylinder when used

as a self contained heating system (with hose and

regulator). Larger tanks may be used if installed

in a permanent gas supply system.

The propane/LP cylinder used must include a

collar to protect the cylinder valve and a listed

overlling prevention device (OPD).

IMPORTANT: You must use a propane/LP gas

supply cylinder that is compatible with the connec-

tion device provided with the hose and regulator.

1. Remove 90° gas tting from hardware bag.

2. Apply pipe joint sealant lightly to male NPT

threads (see Figure 10). This will prevent excess

sealant from going into pipe. Excess sealant in

pipe could result in clogged heater valves.

3. Hold gas pressure regulator with wrench when

connecting the 90° gas tting. Do not over

tighten connection to regulator. The regulator

body could be damaged.

4. Provide propane/LP supply system (see Pro-

pane/LP Supply, page 5).

Connect fuel gas tting on hose/regulator assem-

bly to propane/LP tank(s). Turn fuel gas tting

counterclockwise into threads on tank. Tighten

rmly using a wrench. IMPORTANT: Position

regulator so that hose leaving the regulator is

in a horizontal position (see Figure 11). This

places the regulator vent in the proper position

to protect it from the weather.

6. Connect hose to heater inlet. Tighten rmly

using a wrench. You must use the regulator

supplied with heater.

Open propane/LP supply valve on propane/LP

tank(s) slowly. Note: If not opened slowly,

excess-ow check valve on propane/LP tank

may stop gas ow. If this happens, close pro-

pane/LP supply valve and open again slowly.

Check all connections for leaks. Apply a noncor-

rosive leak detection uid to gas joints. Bubbles

forming show a leak that must be corrected.

9. Close propane/LP supply valve.

Installation Items

Before installing heater, make sure you have the

items listed below.

• external regulator (supplied by installer)

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• equipment shutoff valve *

• ground joint union

• test gauge connection *

• sediment trap

• tee joint

• pipe wrench

* A CSA design-certied equipment shutoff valve

with 1/8" NPT tap is an acceptable alternative to

test gauge connection. The optional CSA design-

certied equipment shutoff valve can be purchased

from your dealer. See Accessories, page 17.

If installing to a xed fuel piping system, the

installation must conform with local codes or, in

the absence of local codes, with the National Fuel

Gas Code, ANSI Z223.1.

If the heater will be connected to a permanent

gas source, the installer must supply an external

regulator. The external regulator will reduce in-

coming gas pressure. You must reduce incoming

gas pressure to between 11" and 14" of water. If

you do not reduce incoming gas pressure, heater

regulator damage could occur. Install the external

regulator with the vent pointing down as shown

in Figure 12. Pointing the vent down protects it

from freezing rain or sleet.

CAUTION: Use only new,

Installation must include equipment shutoff valve,

union and plugged 1/8" NPT tap. Locate NPT tap

within reach for test gauge hook up. NPT tap must

be upstream from heater (see Figure 13).

IMPORTANT: Install an equipment shutoff valve

in an accessible location. The equipment shutoff

valve is for turning on or shutting off the gas to

the appliance.

Apply pipe joint sealant lightly to male NPT

threads. This will prevent excess sealant from

going into pipe. Excess sealant in pipe could result

in clogged heater valves.

1. Disconnect appliance with its appliance main

gas valve (control valve) and equipment

shutoff valve from gas supply piping system.

Pressures in excess of 1/2 psig will damage

heater regulator.

2. Cap off open end of gas pipe where equipment

shutoff valve was connected.

3. Pressurize supply piping system by opening

propane/LP supply tank valve or using com-

pressed air.

4. Check all joints of gas supply piping system.

Apply a noncorrosive leak detection uid to

all joints. Bubbles forming show a leak.

5. Correct all leaks at once.

6. Reconnect heater and equipment shutoff valve

to gas supply. Check reconnected ttings for

leaks.
