When installing a shelf over the top of the replaces, the following
guidelines must be adhered to:
For Rear Vent applications, the minimum clearance is 2" from the rear
of the replace to a wall, or any combustible materials. A clearance

For Top Vent applications, the minimum clearance is 2" from the rear of

underside of any combustible shelf materials, Figure 4.
For Top or Rear Vent applications where the Minimum mantel height

2. Secure the BSR Frame to the exterior sheathing of the structure.
1. Frame the MOSR opening to 12" x 12".
2. Fasten the MOSR frame to the interior side of the studs, concrete,
or nished wall construction using a minimum of 4 screws.
3. Insert the termination into the MOSR frame as shown here, (from
the inside) and attach to the MOSR by installing a min. quantity of
4 bolts into the threaded nuts on the MOSR Frame.

installations where the termination is located within 7' feet above
grade, or above a pedestrian walkway, and may be Required by code
in Public areas.
1. Ensure that the two longmounting brackets are facing the bottom
of the termination. (See inset). This will provide more heat protection
at the top of the termination, where temperatures are highest.
2. Attach to the faceplate of the termination using four sheet metal
screws.

Connection and installation of the vent components should
adhere to the following guidelines:
Montigo recommends the use of a ex section for the nal pipe
connected directly to the replace offering greater exibility of
installation and absorption of movement.
Firestops must be installed as required by National & local codes.
Montigo recommends that all exterior corners and joints be sealed
with exterior caulking. However, we encourage you to consult
your Building Envelope Engineer or Waterproong Consultant
for further recommendations.

WARNING!
When pressure testing the replace, Gas line, and input system
follow the appropriate local codes or your area. DO NOT connect
the replace to pressures in excess of 1/2lb. This will damage the
gas control valve.
The manifold outlet pressure is set from the factory to the
appropriate pressure but should be veried.
To check pressures, control valves have a provision to remove
a 1/8” N.PT. plug to be tted with a hose barb.
Montigo requires a service shut off valve be located in an
accessible location to isolate the gas supply.
Only install gas shut-off valves approved for use by the state,
province, or other governing body in which the replace is being
installed.

Mantels & Surrounds
 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!
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,
discolouration or premature failure of T.V. radio, and other electronic
components.
