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. 

■ Verify that your replace is compatible with your available gas
type. (Natural Gas or Propane shown by "N" or "L" in your model
number
■ If gas type is not compatible, contact your local Montigo
representative to purchase a conversion kit.
■ Conversion kits must be installed by a qualied service technician.

■ Optimum appliance performance requires proper input pressures.
■ Gas line sizing requirements will be determined in ANSI Z223.1
National Fuel Gas Code in the USA and CAN/CGA B149 in
Canada.
Pressure requirements are:

■ 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.

■ See Figure 23 for location of gas line access.
■ 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.
■ Check appliance connection, valve and valve train under normal
operating pressure with a commercially available leak check
solution.

Glass doors on gas fireplaces are extremely hot while the fireplace is on and
remain hot even after the fireplace has been turned off. Safety screens are
available and can reduce the risks of severe burns. Please keep children away
from the fireplace at all times.
CAUTION
Do not use ammonia based or abrasive cleaners on the glass, they will permanently
etch the surface. Use an approved gas fireplace glass cleaner such as Kel-Kem or
White off.
NOTICE
When pressure testing the fireplace, Gas line, and input system, follow the
appropriate local codes for your area. connect the fireplace to pressures
in excess of 1/2lbs. This will dampage the gas control valve.
