RDVN Series Direct Vent Gas Fireplace
Gas Line Installation
When purging gas line, the front window
frame assembly must be removed.
1. The gas pipeline can be brought in through the rear
of the fireplace as well as the bottom. Knockouts are
provided on the bottom behind the valve to allow for
the gas pipe installation and testing of any gas con-
nection. It is most convenient to bring the gas line in
from the rear right side of the valve as this allows fan
installation or removal without disconnecting the gas
line.
The gas line connection can be made with properly
tinned 3/8" copper tubing, 3/8" rigid pipe or an ap-
proved flex connector. Since some municipalities
have additional local codes, it is always best to con
sult your local authority and the National Fuel Gas
Code, ANSI Z223.1/NFPA 54 in the USA or the CSA-
B149.1 installation codes.
*Adhere to the following installation requirements in the State
of Massachusetts:
•
The installer must be a licensed plumber or gas fitter.
•
Flex connectors must be Massachusetts approved, cannot
exceed 36" (914mm) in length, must be a minimum 1/2"
dia. and may not penetrate a wall.

Fig. 5 Typical gas supply installation.
2. The gas control inlet is 3/8" NPT typical installation
layout for rigid pipe is shown in Figure 5.
NOTE: All models are equipped with a flex tube
with a shut off valve having a 1/2" NPT inlet. The
flex line with shut off is shipped in the control
valve compartment. Using two wrenches, tighten
the flexible tube at the shut off valve and at the
gas control
3. When using a flex connector,* use only approved fit-
tings. When a union is installed, provide easy access
in its placement for servicing. Refer to gas specifica-
tion for pressure details and ratings.
4. When a vertical section of gas pipe is required for
the installation, a condensation trap is needed. In
Canada see CSA-B149.1 for code details. See the
National Fuel Gas Code ANSI Z223.1/NFPA 54 in
the USA.

5. For natural gas, a minimum of 3/8" iron pipe with a
gas supply pressure of 4.5" w.c. (from the gas me-
ter). Consult with local gas utility and ANSI Z223.1/
NFPA 54 if any questions arise concerning pipe
sizes.
6. Turn the gas supply to 'ON' and check for leaks. DO
NOT USE OPEN FLAME FOR THIS PURPOSE.
Use an approved leak testing solution.
7. The appliance and its appliance main gas valve
must be disconnected from the gas supply piping
system during any pressure testing of that system at
test pressures in excess of 1/2 psig (3.5KPa).
8. This appliance must be isolated from the gas supply
piping system by closing its equipment shut off valve
during any pressure testing of the gas supply piping
system at test pressures equal to 1/2 psig (3.5KPa).
Always check for gas leaks with a mild soap and
water solution. Do not use an open flame for leak
testing.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to pro-
vide a 1/8" test point up stream of the control.
When using copper or flex connector use only approved
fittings. Always provide a union when using black iron
pipe so that the gas line can be easily disconnected for
burner or fan servicing. Refer to the gas specifications
for pressure details and ratings.
The fireplace valve must not be subjected to any test
pressures exceeding 1/2 psi. Isolate or disconnect this
or any other gas appliance control from the gas line
when pressure testing.

Installation:
1. Thread the wiring through holes on the end panels
of appliance. Take care not to cut wire or insulation
on metal edges. Route the wire to a conveniently
located receptacle box.
2. Attach the wire to the ON/OFF switch and install the
switch into the receptacle box.
3. Connect the other ends of the wire to the gas control
valve. (Fig. 6)
