CALIBER DIRECT VENT INSTALLATION INSTRUCTIONS
Note:
This appliance and its individual 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).
2. Gas Line Connection
The appliance is provided with a stainless steel
flexible connector and a listed (and Commonwealth
of Massachusetts approved) tee-handle manual
shutoff valve. See Figure 47. 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. See Figure 48 to connect
the gas line.
Optional:
Seal around the gas line to
prevent cold air leakage.
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.
3. Gas Pressure
A pressure tap is included on the front face of the standing pilot and electronic gas control 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. Field Fuel Conversion Instructions
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 appliance must be converted to use: Propane/standing pilot -
CKVP
, Natural Gas/standing
pilot -
CKVN
; Propane/intermittent pilot -
DCKVP
, Natural Gas/intermittent pilot -
DCKVN
.

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 building codes by a qualified installer approved and/
or licensed as required by the locality. In the
Commonwealth of Massachusetts, installation must be
performed by a licensed plumber or gas fitter.
