NOVUS SERIES INSTALLATION INSTRUCTIONS
G. UTILITIES
1. HIGH ALTITUDE INSTALLATION
For U.S. installation, appliances are tested and approved for elevations from 0-2000 feet. When installing this appliance
at an elevation above 2000 feet, National Fuel Gas Codes require a decrease of the input rating by changing the
existing burner orifice to a smaller size. Input should be reduced 4% for each 1000 feet above sea level. Check with
the local gas utility for proper orifice size identification. The correct orifice is available from your Hearth & Home
Technologies distributor.
For Canada, appliances are certified for elevations from 0-4500 feet. When installing this appliance at an elevation
between 0-4500 feet in Canada, the input rating does not need to be reduced. When installing this appliance at an
elevation above 4500 feet in Canada, check with local authorities.
2. GAS LINE CONNECTION
Open the control access panel (Figure 38) and remove by releasing the spring latch on the left hand side (Figure 39). The
appliance is provided with a stainless steel flexible connector and manual shutoff valve. The incoming gas line should be
piped into the valve compartment and connected to the 1/2 FIP connection provided on the manual shutoff valve. See
Figure 40 to connect the gas line.
All connections must be tightened and checked for leaks with a soap and water solution or a leak detector.
Bleed the gas line to extract any air that may have been trapped inside the pipe.
Optional: Seal around the gas line to prevent cold air leakage.

Note:
This appliance and its manual shutoff valve must be disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in excess of 1/2 psi (3.5 kPa). The appliance must be isolated
from the gas supply piping system by closing its manual shutoff valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).
