PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
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 either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve
located on or near gas meter for natural gas
or using compressed air.
4. Check all joints of gas supply piping system.
Apply noncorrosive leak detection fluid 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 fit
-
tings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 18).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve
located on or near gas meter for natural gas
or using compressed air.
3. Check all joints from gas meter to equipment
shutoff valve for natural gas or propane/LP
supply to equipment shutoff valve for propane/
LP (see Figure 19 or 20). Apply noncorrosive
leak detection fluid to all joints. Bubbles form
-
ing show a leak.
4. Correct all leaks at once.

PRESSURE TESTING HEATER GAS
CONNECTIONS
1. Open equipment shutoff valve (see Figure 18).
2. Open main gas valve located on or near gas
meter for natural gas or 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 thermostat gas valve (Thermostat-
Controlled Models), to control valve (Manu
-
ally-Controlled Models) or to gas control
(Remote-Ready Models) (see Figures 19 and
20). Apply noncorrosive leak detection fluid
to all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light heater (see
Operating Heater
, page 19).
Check all other internal joints for leaks.
7. Turn off heater (see

ance
, page 20 for Thermostat-Controlled mod
-
els, page 22 for Manually-Controlled Models
or page 24 for Remote-Ready Models).
