GAS PIPE INSTALLATION

CHECK GAS TYPE

Use proper gas type for the fi replace you are installing.
If you have confl icting gas type, do not install fi replace.
See dealer where you purchased the fi replace for proper
fi replace for your gas type or conversion kit.
A qualifi ed installer or service person must
connect appliance to gas supply. Follow all
local codes.

INSTALLATION ITEMS NEEDED

Before installing fi replace and burner system, make sure
you have the items listed below.
•
External regulator
•
Piping (check local codes)
•
Equipment shutoff valve*
•
Tee joint
•
Sediment trap (recommended)
•
Sealant (resistant to propane/LP gas)
(supplied by installer)
•
approved fl exible gas line with gas connector (if
allowed by local codes — not provided)
* A CSA design-certifi ed equipment shutoff valve with
1/8" NPT tap is an acceptable alternative to test
gauge connection. Purchase the CSA design-certifi ed
equipment shutoff valve from your dealer.
For propane/LP connections only, 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 13 inches of water. If you do
not reduce incoming gas pressure, burner system regula-
tor damage could occur. Install external regulator with the
vent pointing down as shown in Figure 51. Pointing the
vent down protects it from freezing rain or sleet.
For propane/LP units, never connect
fi replace directly to the propane/LP supply.
This burner system requires an external
regulator (not supplied). Install the external
regulator between the burner system and
propane/LP supply.

Use only new black iron or steel pipe.
Internally tinned copper or copper tubing
can be used per National Fuel Code, Section
2.6.3, providing gas meets hydrogen sulfi de
limits, and where permitted by local codes.
Gas piping system must be sized to provide
minimum inlet pressure (listed on data plate)
at the maximum fl ow rate (BTU/hr). Undue
pressure loss will occur if the pipe is too
small.
When using copper or fl ex connectors use only fi ttings
approved for gas connections. The gas control inlet is
3/8" NPT.
