VWDV70 Series Gas Fireplace
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.
INSTALL GAS PIPING TO FIREPLACE
LOCATION
Before installing fi replace and burner system, make sure
you have the items listed below.
•
External regulator (supplied by installer)
•
Piping (check local codes)
•
Equipment shutoff valve*
•
Sealant (resistant to propane/LP gas)
•
Test gauge connection*
•
Sediment trap (recommended)
•
Tee joint
•
Pipe wrench
•
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 equip-
ment 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 regulator
damage could occur. Install external regulator with the vent
pointing down as shown in Figure 35. 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.

When using copper of fl ex connectors use only fi ttings
approved for gas connections. The gas control inlet is
3/8" NPT.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to provide
a 1/8" test point up stream of the control.
Always provide a union when using black iron pipe so
the gas line can be easily disconnected for burner or fan
servicing. Refer to gas specifi cations for pressure details
and ratings.
The fi replace valve must not be subjected to any test
pressures exceeding 1/2 psi. Isolate or disconnect this and
any other gas appliance control from the gas line when
pressure testing.
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.
