This appliance and its individual shuto valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of ½ psi (3.5 kPa).
Test Pressures Equal To or Less Than 1/2 psi (3.5 kPa)
This appliance must be isolated from the gas supply
piping system by closing its individual manual shuto
valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than ½ psi (3.5
kPa).

safety concerns.
Do not use this appliance if any part of it has been under
water. Immediately call a qualied service technician to
inspect the appliance and to replace any part of the control
system and any gas control that has been under water.
Improper installation, adjustment, alteration, service or
maintenance can result in injury or property damage. For
assistance or additional information, consult a qualied
installer, service agency or the gas supplier.
Do not store or use gasoline or other ammable vapors or
liquids in the vicinity of this appliance.
INITIAL LIGHTING INSTRUCTIONS
1. Purge air from the supply line as follows:
• Open the main shuto valve.
• Unscrew the main pressure test point on the appliance regulator
• Leave the inlet test screw open until gas ows in.
• When the gas is owing, tighten the inlet screw immediately.
2. Test for leaks in each of the following locations:
• The gas supply line connection to the main valve;
• The Burner connections and pilot;
• All joints on the valve and control body;
• All eld made joints and gas shuto valves;
• All factory made joints and connections.
3. You may check for gas leaks using one of the following methods only:
• Soap and water solution. WARNING: If using a soap and water solution to test
for leaks, DO NOT spray the solution onto electronic parts;
• An approved leak testing spray;
