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 1" from the rear of
the replace to a wall, or any combustible materials, and 13" clearance
from the top of the replace to the underside of any combustible shelf
materials.
For Top Vent applications, the minimum clearance is 1" from the rear
of the replace to a wall, or any combustible materials, and 17 1/2" to
the underside of any combustible shelf materials.
1” clearance is maintained on sides and bottom of vent runs and 2”
above horizontal vent runs to any combustible material.

To avoid elevated mantel temperatures, all H*38C* 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 as shown in  ensuring that the height of the
standoff maintains a 4" clearance from the top of the unit to the 1st

The 4" nailing ange extension is shipped attached to the top edge of

The maximum termination point is 32’ above the replace (NOTE:
if the maximum termination height is used, the ame pattern
may be affected).
The Vertical termination must be a minimum 2’ higher than where
the termination exits the roong materials, (asphalt shingles,
cedar shakes, etc). This distance should be measured from the
high side of the roof slope where the ue ashing intersects the
roong materials. (see Figures 9 to 9c).
Termination location must be a minimum 6’ from a mechanical
air inlet.
Termination location must be a minimum 18” from a parapet wall.
For a more detailed diagram of allowed termination locations,
see .
A maximum of two offsets (each offset is made up of 2-90°
bends) may be made.
Firestops must be installed as required by National & local codes
Ensure all runs are supported with a minimum of 3 supports
per 10’ of venting.
Install all roof ashing and storm collars as shown.

All dimension lengths for vertical or horizontal runs are measured
from center of the vent pipe.
Venting runs must fall within the limits set by the venting graphs,
see Figure 12 or 12a.

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.
Use any combination of rigid and ex pipe as required and in
any orientation (Male connectors can face in any direction).
Flex sections may be stretched up to 50% of their total length
(e.g. a 24” section maybe stretched to 36”).
Connect all vent sections using a minimum of three sheet metal
screws on the outer pipe ue.
Ensure the pipe ends male to female slide in a minimum of 1
1/2” of overlap.
Ensure all runs are supported with a minimum of 3 supports
per 10’ of venting.
When hanging/ supporting venting, ensure that 1” clearance
is maintained on sides and bottom of vent runs and 2” above
horizontal vent runs to any combustible material.
Rigid pipe may be cut less than half way from the
Ensure when cutting sections of rigid pipe to maintain integrity
of internal supports.
Place the springs, supplied with the pipe kit, between the outer
and inner pipes to keep the pipes separate and avoid any
possible hot spots.

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,

Flexible gas connectors must not exceed 3 feet in length, unless
allowable within local regulations.
Connect incoming gas line to the 1/2"or 3/8" gas inlet port.
Purge all air out of gas line.

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 a 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. A fire or explosion
will occur, causing serious injusy, property damage or death.
DANGER
When pressure testing the fireplace, Gas line, and input system follow the appropriate
local codes or your area. DO NOT connect the fireplace to pressures in excess of
1/2lb. This will damage the gas control valve.

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.
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. radio, and other electronic components.
