HEARTH EXTENSION
If there is a combustible floor construction in front of the fireplace,
a hearth extension is recommended to protect it. For the hearth
extension recomend you project a minimum of 6" beyond the sides
of the fireplace opening and a minimum of 12" in front of it. The
hearth extension must be made from a non-combustible material,
such as tile, slate, marble, etc. Consult your local Gas Inspection
Branch should you decide to install your gas fireplace without a
hearth extension.
Vent Runs straight up
8'(minimum)-10': use 8" B-Vent
(no Offsets)
greater than 10': use 7" B-Vent
Vent Runs with a

45 degree Offset
greater than 18': use 7" B-Vent
Vent Runs with a

greater than 18': use B-149 vent
sizing chart
If using the B-149 sizing chart, select a B-Vent size that
will accomodate 200,000 BTUs (5 times the BTU rating
of the Montigo36SR).
INSTALLING SAND, LOGS AND EMBERS
Montigo 36SR Fireplaces are supplied with four cultured oak logs,
sand and embers to help create an attractive and realistic fire. To
install simply add the white silica sand until burner tray is filled to
the top; an inadequate amount of sand may cause excessive sooting.
Place one of the large
logs towards back of pan and fireplace,
making sure that hollow section is facing toward back wall of
fireplace (do not place hollow section facing the sand).
Place the other large log on the sand in about the middle of the
pan (approx. 2" from front of pan to front of log), again making
sure hollow section is facing toward back wall of fireplace.
Sprinkle embers on all exposed areas of sand, particularily in
front of the smaller log. Two small logs may be placed across
large logs at random to create desired flame and log positions
to simulate "Real Life Fire". See figure 4.
Test your B-Vent installation after completion to assure that no
combustible by-products are spilling from the fireplace opening.
This draft test should be performed after a three minute warm up
period. Canadian Heating Products Inc. will not be responsible
for any installations with inadequate draw.
Montigo 36SR uses 7" B-Vent and requires no B-Vent appliance
connector. Fasten the B-Vent to the L-shaped brackets on each side
of the opening with 1/4" sheet metal screws. Do not penetrate the
inner sleeve of the B-Vent when tightening the screws. Refer to the
current CAN/CGA B-149 Gas Installation Code for specific vent
sizing installation instructions. The following table is provided as a
guide for types of B-Vent to use with common installations. These
values have been formulated to include a margin of safety to ensure
safe operation in most typical installations.

INSTALLING THE GAS LINE
The gas line must be installed before finishing the Montigo 36SR
fireplace. The gas control valve (which is mounted behind the
removable grille at the bottom of the unit), is connected to the gas
line through the access opening which is provided on the left side.
FIREPLACE MANTLE AND FACING
Combustible mantles may be safely installed over the top of the
fireplace, provided they do not project beyond a line from point A
to point B, as illustrated in the left side of Figure 3 below. Combustible
materials may also be installed next to the sides of the fireplace,
provided they do not project beyond the shaded area illustrated in the
right side of Figure 3.
FIGURE 3. COMBUSTIBLE FACINGS
When selecting the finish material for your fireplace, it is important
to remember the following: GRILLES MUST NOT BE
OBSTRUCTED IN ANY WAY; to do so restricts the air supply
for the control compartment and 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 operation of the glass doors.

INSTALLATION OF B-VENT
*After gas line is connected, it is a CAN/CGA B149 1 & 2 . code
requirement (Section 8.25.3 (e)) that "each appliance connection,
valve, valve train, shall 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. DO NOT use
a flame of any kind to test for leaks.
