WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical 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.
• If you smell gas, shut off control valve, open doors and windows, and do not
use any electrical device. Call our technical department at [phone].
After completion of gas pipe connections, all joints must be checked for gas-tightness by means of leak detector solution,
soapy water or an equivalent solution, as applicable.
CAUTION: Since some leak test solutions, including soapy water, may cause corrosion or stress cracking, all tested pipes
and joints shall be rinsed in water, unless it has been determined that the test solution is a non-corrosive type.
Shut off valve
Any compound used on the threaded gas piping joint shall be resistant to any
action of liquefied petroleum gas.
A shut off valve (or appliance connector valve) must be installed in the gas line
upstream to permit servicing.

ATTENTION INSTALLER: INSTRUCT YOUR CUSTOMER ABOUT THE CORRECT
OPERATION OF THE APPLIANCE BEFORE YOU LEAVE.
Air must be exhausted from pipeline by depressing to pilot setting or by loosening gas inlet connection until you smell gas. Qualified ser-
vice persons must conduct this procedure only for the first time the heater is operated, in a well ventilated room, with doors and windows
open. If loosened, tighten gas inlet connection. Check gas inlet connection with a soapy water solution to assure no leaks are present.
Do not regulate primary air burner. They both have been adjusted according to corresponding gas. If burner produces a permanent bright
yellow flame when igniting or when ignited, call: [phone].
Connection

carefully checking all connections with a soapy water solution to assure

OPERATING INSTRUCTIONS
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.
A) This appliance has a pilot which must be lighted by hand. When 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 electrical 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 hands to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, do not
try to repair it; call a qualified service technician. Force or attempted repair may result in a fire or explosion.
D) Do not use this appliance if it has been under water. Immediately call a qualified service technician to inspect the heater and to
replace any part of the control system and any gas control which has been under water.
NOTE: It is normal for the new heater to give off some odor the first time it is lit. This is due to final paint curing and to any un-
detected oil remaining from the manufacturing process. It is recommended that you operate your new wall heater for at least two
(2) hours the first time you use it.
ONCE THE UNIT IS IN OPERATION, CHECK ALL GAS CONNECTIONS WITH A SOAPY WA-
TER SOLUTION. CHECK THE TEST POINT PRESSURE; IT MUST BE 3.5" W.C. FOR NATURAL
GAS AND 10.0" W.C. FOR LP GAS.
