RDV4136 Series Direct Vent Gas Fireplace
10010618
A hearth is not mandatory but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth which projects out 12” (305mm) or more from the
front of the fireplace.
Cold climate installation recommendation:
When installing this unit against a non-
insulated exterior wall or chase, it is
mandatory that the outer walls be insulated
to conform to applicable insulation codes.
Hearth
Noncombustible materials such as brick or tile may be
extended over the edges of the face of the appliance.
DO NOT cover any vent or grille panels.
If a Trim Kit is going to be installed on the fireplace, the
brick or tile will have to be installed flush with the edges
of the appliance.

Check fireplace to make sure it is levelled
and properly positioned.
To mount the appliance:
1. Choose the location.
2. This unit comes with four (4) flanges pre-mounted
on both sides of the fireplace to allow two different
drywall thicknesses to be used. Flange “A” is for 1/2”
drywall while flange “B” is for 5/8” drywall.
3. Bend the desired flanges out 90° on both sides of
the fireplace. Slide the fireplace into the framed
opening until the flanges contact the front surfaces
of the framing. Level the unit and secure it firmly in
place.

High Elevations
Input ratings are shown in BTU per hour and are
certified without deration for elevations up to
4,500 feet (1,370m) above sea level.
For elevations above 4,500 feet (1,370m) in USA,
installations must be in accordance with the cur-
rent ANSI Z223.1/NFPA 54 and/or local codes hav-
ing jurisdiction.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370m).
When purging gas line, the front window
frame must be removed.
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 connection.
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 approved
flex connector. Since some municipalities have ad-
ditional 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 installa-
tion codes.
