Installation Items Needed
Before installing appliance, make sure you have the items listed below�
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connector (if allowed by local
codes) (not provided
)
* An equipment shutoff valve with 1/8" NPT tap is an acceptable al-
ternative to test gauge connection� Purchase the optional equipment
shutoff valve from your dealer�
WARNING: This appliance requires a 1/2" NPT
(National Pipe Thread) inlet connection to the pres-
sure regulator.
WARNING: A qualified service person must con-
nect appliance to gas supply. Follow all local codes.
CONNECTING TO GAS SUPPLY
WARNING: Never connect this appliance to private
(non-utility) gas wells. This gas is commonly known
as wellhead gas and does not have odorants and may
have impurities, and variations in BTU content. The
use of well-head gas will void the manufacturer’s
warranty to this appliance.
When an appliance is for connection to a fixed piping
system, the installation must conform with local codes, or
in the absence of local codes with the
National Fuel Gas
Code
, ANSI Z223.1 • NFPA 54;
National Fuel Gas Code.
CAUTION: Use only new, black iron or steel
pipe. Internally-tinned copper tubing may be used
in certain areas. Check your local codes. Use
pipe of 1/2" diameter or greater to allow proper gas
volume to appliance. If pipe is too small, undue loss
of volume will occur.
Installation must include an equipment shutoff valve, union and
plugged 1/8" NPT tap� Locate NPT tap within reach for test gauge
hook up� NPT tap must be upstream from appliance
(see
Figure B).
IMPORTANT
:
Install equipment shutoff valve in an accessible loca-
tion� The equipment shutoff valve is for turning on or shutting off
the gas to the appliance�
Check your building codes for any special requirements for locating
equipment shutoff valve to appliances�
Apply pipe joint sealant lightly to male NPT threads� This will prevent
excess sealant from going into pipe� Excess sealant in pipe could
result in clogged appliance valves�
