Installing The Fireplace Shell
The replace may be installed in any location that maintains proper clearances to air conditioning ducts, electrical wiring and plumbing. Safety,
as well as efciency of operation, must be considered when selecting
the replace location. Try to select a location that does not interfere
with room trafc, has adequate ventilation, and offers an accessible
pathway for Direct Vent installation. Refer to page 4 - Vent Installation
for more information.

Unprotected combustible walls which are perpendicular to the replace

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.

Installation
Installing The Gas Line
The gas line must be installed before nishing the H-Series BF Fireplace.
Natural Gas requires a minimum inlet gas supply pressure of 5.5" W.C.
& a manifold pressure of 3.5" W.C. Propane Gas requires a minimum
inlet gas supply pressure of 11" W.C. & a manifold pressure of 10" W.C.
Provision must also be made for a 1/8" N.P.T. plugged tapping and be
accessible for test gauge connection immediately upstream of the gas
supply controls to the appliance. The replace gas connection and
the main operating gas valve is located behind the removable trim at
the bottom of the unit and need only be attached to the gas line with
an approved tting, as required by the applicable installation codes.
To access the replace gas connection the main burner must be
removed as shown below in gure 4b.
• Only use gas shut-off valves approved for use by the state, province,
region, or governing body, in which the appliance is being installed, or
as required by the applicable installation codes.
• Flexible gas connectors must not exceed 3 feet in length, unless it is
allowable within applicable installation codes.
Vent Installation
The H-Series BF is certied for use with standard 4" B-Vent and requires
no B-Vent appliance connector. Simply attach the B-Vent to the replace
ue collar, and secure it using 1/4" sheet metal screws.
Refer to the current CAN/CGA B-149.1 and .2 or ANSI Z223.1-1998
Gas Installation Code for specic vent sizing.
Note: If more than 12 feet of B-Vent is used on the vent
runs, use ceiling supports.
Cautions:
■ Test your B-Vent installation after completion to ensure that
no combustible by products are spilling from the replaces
opening. This draft test should be performed after a three(3)
minute warm up period. The manufacturer will not be
responsible for any installations with inadequate draw.
Note: Due to the top vent clearances to combustible
materials there is no available shelf installation for
the H-Series BF replaces.
Figure 4a. Gas line access.
The appliance and its individual shut-off 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 (3.5 kPa).
The appliance must be isolated from the gas supply piping system by
closing its individual manual shut-off valve during any pressure testing
of the gas supply piping system at test pressures equal to or less than
1/2 psig (3.5 kPa).
Note: After gas line is connected, each appliance connection,
valve and valve train must be checked while under normal
operating pressure with either a liquid solution, or leak
detection device, to locate any source of leak. Tighten any
areas where bubbling appears or leak is detected until
Page 4
bubbling stops completely or leak is no longer detected.
DO NOT use a flame of any kind to test for leaks.
Installing The Standoffs
To avoid elevated mantel temperatures, all H-Series BF gas
replaces are required to have the supplied standoffs installed.
The replace is supplied with two standoffs. Bend and install these
standoffs on top of the replace ensuring that the height of the standoff
maintains a 6" clearance.
Figure 5. Installing the standoff's.
Installing the Nailing Flange
Extension
Once the replace is placed into the framed opening, the supplied
nailing extension must be placed along the top edge of the replace,
and nailed in place to the framing, as illustrated below.
Figure 6. Installing the Nailing Flange Extension.

Installation
H-Series BF Gas Fireplace
Installing The Remote Switch
The H-Series BF's gas valve, located behind the lower trim, may be
connected to a wall switch. The valve generates its own power on a
millivolt circuit. Use only low voltage wire, and DO NOT connect
any external power to it.
Refer to Figure 30 for wiring requirements.
Note: The switch location must not exceed 30' from the replace.
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 7. Side wall clearances are 3".
Combustible surrounds may be installed with 3" clearance to the side
of the replace as shown in Figure 8.
Fireplace Facing
When selecting the nish material for your replace, it is important to
remember the following: THE PERFORATED VALVE COVER MUST
NOT BE OBSTRUCTED IN ANY WAY - to do so restricts the air
supply for the control compartments and heat exchanger it also
prevents access for servicing controls.
The face of the replace may be painted to match the room decor,
provided you use a heat-resistant paint. 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.
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 efcient.
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 with a noncombustible 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.
Painting:
Special care is recommended by the Master Painters and Decorators
Association, when painting the replace surrounds, to select and apply
a quality Alkyd sealer prior to the applying of latex paints. This is to
prevent leaching of water from evaporation and causing a brownish
staining effect to paint over coats.
