WARNING: Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.

Pressure Testing Gas Supply

Piping System

Test Pressures In Excess Of

1/2 PSIG (3.5 K Pa)

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
s y s t e m	b y	e i t h e r u s i n g
compressed		air	or	opening
propane/LP	supply		tank	valve.

4.Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Reconnect heater and equipment shutoff valve to gas supply. Check reconnected fittings for leaks.

Test Pressures Equal To or Less Than 1/2 PSIG (3.5 K Pa)

1.Close equipment shutoff valve (see Figure 14).

2.Pressurize supply piping system by either using compressed air or opening propane/LP supply

tank valve.

3.Check all joints from propane/LP supply tank to equipment shutoff valve (see Figure 14). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.

Pressure Testing Heater Gas Connections

1.Open equipment shutoff valve (see Figure 14).

2.Open propane/LP supply tank valve.

3.Make sure control knob of heater is in the OFF position.

4.Check all joints from equipment shutoff valve to control valve

(see Figure 15 ). Apply mixture of liquid soap and water to gas joints. Bubbles forming show

aleak.

5.Correct all leaks at once.

6.Light heater (see Operating Heater, pages 10,11and 12) Check the rest of the internal joints for

leaks.

7.Turn off heater (see To Turn Off Gas to Appliance, pages 11 and 12).

8.Replace lower front panel.

FOR YOUR SAFETY

READ BEFORE LIGHTING

WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life.

AWhen lighting the pilot, follow these instructions exactly.

B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor .

WHAT TO DO IF YOU SMELL GAS

Do not try to light any appliance. Do not touch any electric switch; do not use any phone in your building.

Immediately call your gas supplier from a neighbor’s

phone. Follow the gas supplier’s instructions.

If you cannot reach your gas supplier, call the fire department.

C. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, don’t try to repair it, call a qualified service technician or gas supplier. Force or attempted repair may result in a fire or explosion.

D.Do not use this appliance if any part has been under water . Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.
