IMPORTANT:
• CONVERSION OF THIS FURNACE REQUIRES SPECIALIZED EQUIPMENT.
CONVERSION MUST BE COMPLETED BY A TRAINED AND QUALIFIED INSTALLER,
SERVICE AGENCY OR GAS SUPPLIER.
• CONNECT THIS FURNACE ONLY TO GAS SUPPLIED BY A COMMERCIAL UTILITY
OR SUPPLIER. PRIVATE GAS WELLS DO NOT GENERALLY PROVIDE GAS WITH
CONSISTENT, UNIFORM AND PREDICTABLE HEATING VALUES AND DENSITIES.
MANY NON-COMMERCIAL WELLS CONTAIN IMPURITIES SUCH AS SULPHUR, WHICH
MAY DAMAGE THE FURNACE. THIS FURNACE CANNOT OPERATE PROPERLY OR
SAFELY USING FUELS OUTSIDE NORMAL COMMERCIAL STANDARDS.
In Canada, the gas piping should be installed in accordance with CAN/CSA-B149.1 and 2, and in accordance
with any local codes.
In the United States, the gas piping should be installed in accordance with (NFGC) NFPA 54 / ANSI Z223.1
and any local codes.
If local codes allow the use of a
fl
exible gas appliance connector, always use a new listed connector. Do not
use a connector, which has previously serviced another gas appliance.
IMPORTANT:
To maintain a good seal in the burner area,
the gas piping through the side panel into
the furnace must be 1/2” Schedule 40 black
iron pipe. The pipe passes through a special
rubber grommet that is custom manufactured
to seal tightly around the gas pipe. (Figure 27)
The gas piping may enter the furnace from either
side. Once the routing of the gas pipe is determined,
select and remove the plastic cap if necessary and
install on other panel, and install the grommet within
the hole.
NOTE
We recommend a union between the gas valve and the side panel to allow easy removal of the burner for
service purposes.
