NOVUS B-VENT INSTALLATION INSTRUCTIONS

F. 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. Orifices are available from your 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

The appliance is provided with a stainless steel flexible connector and manual shutoff valve. See Figure 12. 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 13. All connections must be tightened and checked for leaks with a soap and water solution or leak detector. Bleed the gas line to extract any air that may have been trapped inside the pipe.

Note: The appliance and its manual shutoff valve must be disconnected from the gas supply piping system dur- ing 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).

3.GAS PRESSURE

On the standing pilot gas control valve and the electronic valve, a pressure tap is included on the front face of the valve.

Table 2 shows optimum gas pressure information.

Consult your local gas company for assistance in determining the proper orifice for your altitude or refer to ANSI Z223.1-latest edition, Appendix F.

4.FUEL

Do not burn wood or other material in this appliance.

Natural or propane gas conversions necessary to meet the application need to be made by a qualified technician using Hearth & Home Technologies specified and approved parts.

In the event your standing pilot appliance must be converted to use propane gas, you must use a CKVP conversion kit. To convert to use natural gas, you must use a CKVN conversion kit.

If your intermittent pilot appliance must be converted to use natural gas, you must use a DCKN conversion kit. To convert to propane, use a DCKP conversion Kit.
