Zero Clearance Fireplace Installation
This appliance may be installed in a masonry or factory built/zero clear­
ance (ZC) fireplace. When installing in a ZC fireplace, the ZC grate must
be removed and the ZC damper must be removed or secured open. The
ZC doors, screen, refractory or masonry lining, baffles and smoke shelf
may be removed if necessary to install the gas insert. However, do not cut
or alter the fireplace components. The removal of any parts to facilitate
installation must not alter the integrity of the inner or outer shells of the
fireplace cabinet. Any parts removed must be replaceable if the insert is
taken out of the fireplace or the fireplace clearly marked with a paint stick
that "This fireplace has been altered and is no longer safe to operate."
This appliance is designed to fit into a ZC fireplace with a minimum
firebox height of 19­1/2" (495mm). To facilitate this the hood will need
to be removed and discarded (Note: The screws should be replaced in
the insert body).
If the factory­built fireplace has no gas access hole(s) provided, an ac­
cess hole of 1­1/2" (37.5 mm) or less may be drilled through the lower
sides or bottom of the firebox in a proper workmanship like manner. This
access hole must be plugged with a non­combustible insulation after the
gas supply line has been installed.
Si le foyer préfabriqué ne comporte pas d’orifices d’amenée du gaz, un
orifice d’au plus 37,5 mm (1,5 po) peut être pratiqué, selon les règles
de l’art, dans la partie inférieure des parois ou au fond de la chambre de
combustion. Cet orifice doit être obturé au moyen d’isolant incombustible
une fois la conduite de gaz en place.
The installer must mechanically attach the marking supplied with the gas
fireplace insert to the inside of the firebox of the fireplace into which the
gas fireplace insert is installed.
Conversion from Standard 40,000 BTU To Optional 33,000 BTU Input
To convert input from 40,000 BTUs to 33,000 BTU's, after step 1 remove
and replace the stock burner orifice with the #36 NG orifice supplied in
the optional orifice kit P/N H5924. Pipe dope or other approved gas line
sealant will need to be applied before inserting into bulkhead. The foil
sticker supplied, stating RDV33/SDVI33, will need to be affixed over the
model name RDV40/SDVI40 on the serial number label (located in the
control compartment).
Brick Panel and Log Set Installation
If logs are not installed according to the log installation instructions,
flame impingement and improper combustion could occur and result in
soot and/or excessive production of carbon monoxide (CO), a colorless,
odorless, toxic gas.
The size and position of the log set is critical to achieve a safe, reliable
and attractive flame pattern. Any attempt to use a different log set in the
fireplace will void the warranty and will result in incomplete combustion,
sooting and poor flame quality.
1. Remove the log rack (2 screws) and install the rear log on the retainer.
