Ratings
*High Altitude Installations
Input ratings are shown in BTU per hour and are
certified without deration for elevations up to 4,500
feet (1,370 m) above sea level.
For elevations above 4,500 feet (1,370 m) in USA,
installations must be in accordance with the current
ANSI Z223.1 and/or local codes having jurisdiction.
Heating value of gas in some areas is reduced to
compensate for elevation—consult your local gas utility
to confirm.
For installations at elevations above 4,500 feet (1,370 m)
in Canada, please consult provincial and/or local
authorities having jurisdiction.

Supply Gas
Heater engine 1400MN is used with natural gas.
Heater engine 1400MP is used with propane gas.
The supply pressure must be between the limits shown
in the Ratings section.
The supply connection is 3/8” NPT
male and located on the right hand
side of the firebox.
A shut-offvalve (not supplied)
is required on the supply line to
isolate the unit during service. See
Gas Supply on page 48 for details.
Conversion Kits
The 1400M is supplied as natural gas or propane gas
and is field convertible between fuels. See instructions
packaged with the conversion kits for further
information.
Electrical
The 1400M is designed to run on battery power and
does not require an electrical power source to operate
as a heater. However, it requires electrical power to
operate decorative lighting and optional 1495CFK
Circulating Fan Kit or GV60WIFI WiFi module.
HeatShift™System
The 1400M is designed to allow the installation of the
optional HeatShift System, a convection system that
redistributes the warm air flow away from the fireplace
opening to a more desirable location using natural
convection, without use of a fan.
The warm air flow may be relocated to a position
higher up the wall, or even to another room. The result
is much cooler wall temperatures above the fireplace
opening for locating televisions, artwork, etc.
Please note that the framing and mantel clearances
are affected by the installation of the HeatShift
System. Refer to Appendix D - HeatShift System pages
79–98 for more information.
WARNING
Electrical connection IS NOT ALLOWED
when adapting appliance for outdoor use.
