Gas Installation - Napoleon GVFS20P Installation And Operating Instructions Manual

EXAMPLE 1:
In this example, because there is no door to the adjoining room, the volume of the adjoining room may be
added to the volume of the room with the heater to get a total unconfi ned space.
The total unconfi ned space: 800 + 1200 = 2000 cubic feet.
Maximum BTU/h: 2000x1000 = 40,000 BTU/h
If there are no more fuel burning appliances within this space then the 23,000 BTU/h input of the heater is
suitable to be installed. This also assumes that the construction of this space is not unusually tight.
EXAMPLE 2:
If in this example a solid door separates Room 1 from Room 2, the volume of Room 2 could not be used. In
this case the maximum BTU/h would be:
Maximum BTU/h: 800x1000 = 16,000 BTU/h
This would be considered a confi ned space since it can not support the 23,000 BTU/h input of the heater and it
would be necessary to provide adequate combustion and ventilation air to Room 1.

GAS INSTALLATION

RISK OF FIRE, EXPLOSION OR ASPHYXIATION. ENSURE THERE ARE NO IGNITION SOURCES SUCH
SUPPORT GAS CONTROL WHEN ATTACHING GAS SUPPLY PIPE TO PREVENT DAMAGING GAS LINE.
ALWAYS LIGHT THE PILOT WHETHER FOR THE FIRST TIME OR IF THE GAS SUPPLY HAS RUN OUT
WITH THE GLASS DOOR OPENED OR REMOVED. PURGING OF THE GAS SUPPLY LINE SHOULD BE
PERFORMED BY A QUALIFIED SERVICE TECHNICIAN. ASSURE THAT A CONTINUOUS GAS FLOW IS AT
THE BURNER BEFORE CLOSING THE DOOR. ENSURE ADEQUATE VENTILATION. FOR GAS AND
HIGH PRESSURE WILL DAMAGE VALVE. DISCONNECT GAS SUPPLY PIPING BEFORE TESTING GAS
Installation and servicing to be done by a qualifi ed installer. Do not use open fl ame.
A. Move the appliance into position and secure.
B. If equipped with a fl ex connector the appliance is designed to accept a 1/2" gas supply. Without the
connector it is designed to accept a 3/8" gas supply. The appliance is equipped with a manual shut off
valve to turn off the gas supply to the appliance.
C. Connect the gas supply in accordance to local codes. In the absence of local codes, install to the
current CAN/CSA-B149.1 Installation Code in Canada or to the current National Fuel Gas Code, ANSI
Z223.1 / NFPA 54 in the United States.
D. When fl exing any gas line, support the gas valve so that the lines are not bent or kinked.
E. Check for gas leaks by brushing on a soap and water solution.
