optional air-circulating fan kit is installed, it must be electrically
grounded in accordance with CSA C22.1 Canadian Electrical
Code Part 1 and/or Local Codes.
Installations in the USA must conform to local codes, or in the
absense of local codes to the National Fuel Gas Code, ANSI
Z223.1-1988. If the optional air-circulating fan is installed, it must
be grounded in accordance with local codes or, in the absence of
local codes, with the National Electrical Code, ANSI/NFPA 70-
1987.

Installation
Installing The Fireplace Shell
ME34-BV Homefire
The fireplace may be installed in any location that maintains proper
clearances to air conditioning ducts, electrical wiring and plumbing.
Safety, as well as efficiency of operation, must be considered when
selecting the fireplace location. Try to select a location that does not
interfere with room traffic, has adequate ventilation, and offers an
accessible pathway for Vent and Combustion Air installation. Refer to
page 4 - Vent Installation for more information.

Unprotected combustible walls which are perpendicular to the
fireplace opening, must not project beyond the shaded area shown in
Figure 5b.
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapour barrier. This will
reduce the possibility of a cold-air convection current on the fireplace.

Installing a Shelf Over the Fireplace
When installing a shelf over the top of the fireplace, the minimum
allowable clearance from the top of the fireplace to a shelf is
16".(Proper clearance must be maintained around the vent pipes, as
specified by the B-Vent manufacturer.)
WARNING:
When this appliance is installed directly on carpeting, tile or any
combustible material other than wood flooring, it must be installed
on a metal or wood panel extending the full width and depth of
the appliance.

Installation
Installing The Gas Line
The gas line must be installed before finishing the ME34-BV 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
fireplace gas connection and the main operating gas valve is located
behind the removable brass trim at the bottom of the unit and need
only be attached to the gas line with an approved fitting, as required
by the applicable installation codes.
Figure 4. Gas line access.
During any pressure testing of the gas supply piping that excedes 1/2
psig (3.5 kPa), the appliance and its individual shutoff valve must be
disconnected from gas supply system.
When pressure testing the gas supply piping system at test pressures
of less than or equal to 1/2 psig (3.5 kPa), the appliance must be
isolated from the gas supply piping system by closing its individual
manual shutoff valve.
B-Vent Installation
The ME34-BV is certified for use with standard 4" B-Vent and
requires no B-Vent appliance connector. Simply attach the B-Vent to
the fireplace flue collar, and secure it using 1/4" sheet metal screws.
Do not penetrate the inner sleave of the B-Vent when tightening the
screws.
Refer to the current CAN/CGA B-149.1 and .2 or ANSI Z223.1-1988
Gas Installation Code for specific vent sizing.
CAUTION:
n Test your B-Vent installation after completion to ensure that
no combustible by-products are spilling from the fireplace
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: 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
bubbling stops completely or leak is no longer detected.
DO NOT use a flame of any kind to test for leaks.
Installing The Remote Switch
The ME34-BV's gas valve, located behind the lower brass 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 12 for wiring requirements.
Note: The switch location must not exceed 30' from the fireplace.

Installation
Finishing Around the Fireplace
Combustible mantels and mouldings may be safely installed over the
top and on the front of the fireplace provided that they do not project
beyond shaded area shown in Figure 5a. Side wall clearances are 3".
Combustible surrounds may be installed with 3" clearance to the side
of the fireplace as shown in Figure 5b.
Fireplace Facing
When selecting the finish material for your fireplace, it is important to
remember the following: BRASS TRIMS 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 fireplace may be painted to match the room decor,
provided you use a heat-resistant paint. Decorative facing must not
extend past the fireplace opening at all, because it will interfere with
the access to retainers for removal of glass door.
ME34-BV Homefire
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.

Mantels & Surrounds
NOTE: National Canadian Gas Association mantel test requirements
are for fire 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
fireplaces which are hot, fuel and energy efficient.
Please be aware; temperatures over the mantel will rise above
normal room temperature and walls above fireplace may be hot to
touch.

Painting:
Special care is recommended by the Master Painters and Decorators
Association, when painting the fireplace 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.
