NOVUS PLUS INSTALLATION INSTRUCTIONS
F. UTILITIES
Note:
This appliance and its manual shutoff valve must be dis-
connected 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).
WARNING!
This valve has been preset at the factory. Altering settings
may result in fire hazard or bodily injury.
Note:
Have the gas supply line installed in accordance with build-
ing codes by a qualified installer approved and/or licensed as re-
quired by the locality. In the Commonwealth of Massachusetts,
installation must be performed by a licensed plumber or gas fitter.

1. High Altitude Installation
The Novus Plus is power vented. High altitude gas appliance
considerations are no longer of concern, as long as the gas
appliance is properly installed with the HRV200PLUS properly
balanced (refer to HRV200PLUS manual).
2. Connect the Gas Line
The appliance is provided with a stainless steel flexible
connector and listed (and Commonwealth of Massachusetts
approved T-handle) manual shutoff valve. See Figure 5. The
incoming gas line should be piped into the valve compartment
and connected to the 1/2 in. FIP connection provided on the
manual shutoff valve. All connections must be tightened and
checked for leaks with a commercially available, non-corrosive
leak check solution. Be sure to rinse off the solution when
done leak testing. Bleed the gas line to extract any air that
may have been trapped inside the pipe. See Figure 6 to
connect the gas line. Gas connections may also be made by
taking out the knockout in the bottom pan to allow connection
through the bottom of the appliance.
3. Gas Pressure
On the intermittent pilot gas valve, the inlet pressure and
manifold (outlet) pressure taps are available on the face of
the valve. Pressure taps are immediately upstream of the gas
supply connection and accessible for test gauge connection.
Table 1 shows optimum gas pressure information. Consult
your local gas company for assistance in determining the
proper orifice for you altitude or refer to
ANSI Z223.1-latest
edition, Appendix F
.
4. Fuel Conversion
In the event your appliance must be converted to use propane,
you must use a
DCKVP
conversion kit. To convert your
appliance to natural gas, you must use a
DCKVN
conversion
kit.
