INSTALLATION INSTRUCTIONS Cont...
Natural Gas Pressure Settings:
The inlet supply or line pressure must be a minimum of 4.5” wc (1.1 kPa) and a maximum of
14” wc (3.5 kPa). The gas orifice has a #49 DMS drill size.
ELEVATION INPUT RATING
0-4500 ft. (0-1372 m) 15,000 BTU/hr (4,400 watts)
4500 ft. (1372 m) + 15,000 BTU/hr (4,400 watts) less 4% per 1000 ft. (305 m)
Please contact your local distributor for the appropriate orifice size.
Propane Pressure Settings:
The inlet supply or line pressure must be a minimum of 11” wc (2.8 kPa) and a maximum of
14” wc (3.5 kPa). The orifice has a #57 DMS drill size.
ELEVATION INPUT RATING
0-4500 ft. (0-1372 m) 15,000 BTU/hr (4,400 watts)
4500 ft. (1372 m) + 15,000 BTU/hr (4,400 watts) less 4% per 1000 ft. (300m)
Please contact your local distributor for the appropriate orifice size.
NOTE: THE INPUT RATING SHOULD ALWAYS BE CHECKED AFTER FIRST INSTALLING
THIS APPLIANCE. To do this, reduce the background flow rate to a minimum (this flow should
remain constant for the next part of the test), time the meter, light the fireplace and operate it
on high and take another reading after 15 mins. Check with your gas supplier for the gas BTU
content at your elevation. Input is the rate of flow—background flow multiplied by the heating
value of the gas (cubic feet/hour x BTU per cubic feet). Adjust the manifold pressure so that
the unit does not operate above the rated input. To do this, remove the screw dust cap on the
valve and adjust the screw inside the tube so that the maximum input is correct. Reinstall the
screw dust cap when complete.
ELECTRICAL CONNECTIONS
The DV-520 has available an optional convection fan kit that can be installed into the fireplace
(follow the installation instructions provided with the kit)
If the optional fan kit will not be provided at the same time the unit is installed, have a qualified
electrician run a 120VAC supply line to the lower left side of the fireplace before installing the
appliance into the framing. There should be 18” (460mm) of the supply line free for ease of
connection to the convection fan kits junction box.
