Installing The Fireplace Shell
The replace may be installed in any location that maintains proper clear-
ances to air conditioning ducts, electrical wiring and plumbing. Safety,
as well as efciency of operation, must be considered when selecting
the replace location. Try to select a location that does not interfere
with room trafc, has adequate ventilation, and offers an accessible
pathway for Direct Vent installation. Refer to page 4 - Vent Installation
for more information.
The replace dimensions are shown below:
Figure 2. Framing dimensions.

Front View Side View
Unprotected combustible walls which are perpendicular to the replace
opening, must not project beyond the shaded area shown in Figure 8.
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapor barrier. This will reduce
the possibility of a cold-air convection current on the replace.
Figure 1. Fireplace dimensions.
Clearances
These clearances apply to all dimensions except the framed opening,
where the clearance to combustibles is 0". The H52DFN clearance to
unprotected combustible walls which are perpendicular to the replace
opening, must not project beyond the shaded area shown in Fig. 8.
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapor barrier. This will reduce

Finishing Around the Fireplace
Combustible mantels and mouldings may be safely installed over the
top and on the front of the replace provided that they do not project
beyond shaded area shown in Figure 13. Side wall clearances are 3".
Combustible surrounds may be installed with 3" clearance to the side
of the replace as shown in Figure 14.
Figure 13. Combustible mantles and facings.
Fireplace Facing
When selecting the nish material for your replace, it is important to
remember the following:
If the surround of the replace is to be painted to match the room decor,
heat-resistant paint must be provided . Also, decorative facing must not
extend past the replace opening at all, because it will interfere with the
access to retainers for removal of glass door and access to the lower
compartment.
Mantels & Surrounds
NOTE: National Canadian Gas Association mantel test requirements
are for re hazard prevention to combustible materials.
New technology, to meet consumer and government demands for the
wise use of energy, has prompted us to manufacture many models of
replaces which are hot, fuel and energy efcient.
Please be aware; temperatures over the mantel will rise above normal
room temperature and walls above replace may be hot to touch.
Warning:
When covering the upper metal portion of the replace, up to 6" (as
shown,Fig.13& Fig.14, with a non-combustible material Please Note: The
decorative facing materials may be subject to temperatures in excess of
250° F. This should be considered when selecting facing materials.
We recommend careful consideration be given to the effects of elevated
mantel temperatures which may be in excess of product design, for
example: candles, plastic or pictures. This can cause melting, deformation,
discoloration or premature failure of T.V. and radio components.

Maintenance
WARNING:
Do not attempt to clean glass when hot.
Do not clean glass with abrasive materials as any glass
etching may cause premature glass failure.
General
■Have the replace and installation inspected yearly. The inspection
must include, but is not limited to, the following:
• A visual check of the entire vent system and termination.
• An inspection of the explosion relief appers and the door
gasketing to ensure a proper seal.
• An inspection of the burner, venturi, and primary air openings.
• An inspection of the gas valve, gas components, and pilot ame.
For your convenience a 1/8" manifold pressure tap is supplied
on the gas valve for a test gauge connection. See Figure 32.
• Ensure proper log placement as per this manual.
• Inspection of all optional equipment; fans, thermostats, etc.
■ For Natural Gas this appliance requires a minimum inlet pressure
of 5.5" W.C. and a manifold pressure of 3.5" W.C.
■ For Propane Gas this appliance requires a minimum inlet pressure
of 11" W.C. and a manifold pressure of 10" W.C.
■ Always keep the replace area clear and free of combustible materials,
as well as gasoline and other ammable vapors and liquids.
■ Do not use this appliance if anyparthas beenunderwater. Immediately
call a qualied service technician to inspect the appliance and to
replace any part of the control system and any gas control which
has been under water.
Cleaning
When the replace is rst activated, there may be some smoking and
a visible lm may be left on the glass. This is a normal condition, and is
the result of burning of protective coatings on new metal.
■ Glass must be cleaned periodically to remove any lm (which is
a normal by-product of combustion) which may be visible. Film
can easily be removed by removing the door, as shown on page
15. Handle the door carefully, and clean it with non-abrasive glass
cleaners. One of the most effective products is Kel Kem.
■ Silicone seals on inner door during initial ring will "off gas", leaving
a visual deposit of a white substance on combustion chamber walls.
This can easily be removed using normal household products.
■ Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and rebox free from dust and lint.
■ Logs may be cleaned periodically with a vacuum to remove soot or
other contaminates.
Troubleshooting
If your replace still does not operate correctly, consult your dealer or
the manufacturer.
All service and repairs should be performed by a qualied
agency.
All spare parts, optional fans, and optional trim nishes are available
from your local dealer or the manufacturer.
