Installing Heat Guards over Terminations is recommended
in 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.

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.

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.
CAUTION
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.
