CONNECTING TO GAS SUPPLY
WARNING: A qualified service person must con-

Installation Items Needed
Before installing heater, make sure you have the items listed below.
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* A CSA design-certified equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge connection. Purchase
the optional CSA design-certified equipment shutoff valve from
your dealer. See Accessories, page 36.
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" diam-
eter or greater to allow proper gas volume to heater. If
pipe is too small, undue loss of volume will occur.
WARNING: Never connect heater to private (non-
utility) gas wells. This gas is commonly known as
wellhead gas.
WARNING: This appliance requires a 1/2" NPT
(National Pipe Thread) inlet connection to the pres-
sure regulator.
