WARNING
WARNING
Failure to properly pipe gas supply to appliance may
result in improper operation and damage. Always
assure gas piping is absolutely leak free and of the
proper size and type for the connected load.
An additional gas pressure regulator may be
needed. Consult gas supplier.
Failure to use proper thread compounds on all gas
connections may result in leaks of flammable gas.
Gas supply to appliance and system must be
completely shut off prior to installing or servicing
the gas piping.
Do not use matches, candles, or other open flame
ignition source to check for leaks.
Use two wrenches when tightening gas piping at
the appliance, use one wrench to prevent the gas
train from turning.
Failure to support the connection pipe could
damage safety components.
Ensure that the high gas pressure regulator is at
least 10 feet (3 m) upstream of the appliance.

NOTICE
NOTICE
Use lock-up type gas pressure regulator when
low and high gas pressure switches are installed.
Older or non-lock-up type regulators may result in
nuisance lockouts on gas pressure drops or spikes.
The AMP and all other appliances must be firing at
maximum capacity to properly measure the inlet
gas pressure.
