IMPORTANT WARNING AND SAFETY INSTRUCTIONS

Risk of ﬁre or explosion from incorrect fuel use or faulty fuel

conversion. Do not try to run a heater set up for natural gas on propane

gas or vice versa. Only qualiﬁed service technicians should attempt to

convert heater from one fuel to the other. Do not attempt to alter the

rated input or type of gas by changing the oriﬁce. If it is necessary to

convert to a different type of gas, consult your Pentair dealer.

Serious malfunction of the burner can occur which may result in loss

of life. Any additions, changes, or conversions required in order for the

appliance to satisfactorily meet the application needs must be made by

a Pentair dealer or other qualiﬁed agency using factory speciﬁed and

approved parts.

Risk of explosion if a unit converted to propane gas is installed in a

pit or other low spot. Propane is heavier than air. Do not install the heater

using propane in pits or other locations where gas might collect.

Consult your local building code ofﬁcials to determine installation

requirements of heater relative to propane storage tanks and ﬁlling

equipment. In Canada, Installation must meet the requirements of the

Standard for the Storage and Handling of Liquid Petroleum Gases,

CAN/CSA B149.1 (latest edition). In the U.S. installation must meet the

Gas Control Valve Replacement Kit Information

Function

The Combination Gas Control Valve incorporates dual gas shut-off valves and a

negative-pressure regulator. The negative-pressure regulator controls the outlet pres-

sure to slightly below the reference pressure supplied to the regulator diaphragm by

the vent line. For proper operation, the regulated pressure at the outlet manifold of the

valve must be 0.2” wc below the reference pressure, and the gas “vent” tap must be

connected to the Mixer inlet.

Fire and explosion hazard. The Air Oriﬁce is sized speciﬁcally for the air/gas

mixture required by the burner. Do not modify the Air Oriﬁce or replace it with

an oriﬁce of a different size.

Fire and explosion hazard. The Combustion Blower handles a combustible

air/gas mixture. When servicing this part, check all seals for tightness to

ensure that the Blower is not leaking.

Gas Pressure Setting Veriﬁcation

After completing the Servicing Procedure (see page 7) proceed with the following

steps to verify the gas supply pressure.

1. Turn off the electrical supply to the heater.

2. Turn off the pump and shut off the manual gas supply valve to the heater.

3. Use a 3/16” hex key to remove the plug from the PRESSURE TAP port on the

outlet side of the Combination Gas Control Valve.

4. Install a 1/8” NPT barbed ﬁtting into the ‘PRESSURE TAP’ port on the outlet

side of the gas valve. Use a ﬂexible tube to connect it to the low side of a

differential pressure gauge or a slope gauge. This gauge will measure low

(outlet) pressure, which requires a high degree of resolution.

5. Turn on the manual gas shutoff valve.

6. Before operating the heater, leak-test all of the gas connections with soapy

water.

WARNING! Risk of ﬁre or explosion. Never test for gas leaks with an

open ﬂame.

7. Turn on electricity to heater and start the pump.

8. Turn on the heater.

NOTICE: If you are using a slope gauge, close the shutoff valve of the

gauge to avoid pulling the liquid out of the gauge when the blower starts.

9. After the burner lights, verify that the supply pressure is within the range 4” to

12” wc. If the supply pressure drops below this range when the burner ignites,

the gas line capacity may be inadequate, and should be increased.

10. With the burner still on, disconnect the plastic hose between the gas valve and

“VENT” tap and the blower mixer inlet. The pressure gauge should then read

.2” ±.1” wc

. (Since the pressure tap is connected to the low side of the gauge,

the pressure is actually negative.) If the pressure is outside the range listed,

call the factory at

1-800-831-7133.

Do not try to adjust the pressure yourself.
