CONNECTING TO GAS SUPPLY
WARNING: A qualified service person must con-
nect heater to gas supply. Follow all local codes.
CAUTION: Never connect heater directly to the
propane/LP supply. This heater requires an external
regulator (not supplied). Install the external regulator
between the heater and propane/LP supply.
Installation Items Needed
Before installing heater, 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
* 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 28.
The installer must supply an external regulator. The external regulator
will reduce incoming gas pressure. You must reduce incoming gas
pressure to between 11 and 14 inches of water. If you do not reduce
incoming gas pressure, heater regulator damage could occur. Install
external regulator with the vent pointing down as shown in Figure 15.
Pointing the vent down protects it from freezing rain or sleet.
WARNING: This appliance requires a 1/2" NPT
(National Pipe Thread) inlet connection to the pres-
sure regulator.
