Gas Connection - HearthStone CARINA Owner's Manual

Hearthstone Quality Home Heating Products, Inc
Electrical Wiring
This fireplace insert requires 110V AC electrical supply for normal operation in order to power up the Ignition
Control Module that is required to operate the Remote Control. However, during a power outage situation, its
electronic system (Ignition Control) can temporarily be powered with 4 AA batteries. The convection blower will
not function when the unit is operating on backup battery power.
WARNING
Electrical connections should only be performed by a qualified, licensed electrician. Main power must be
off when connecting to main electrical power supply or performing service.
All wiring shall be in compliance with all local, city, and state codes, or in the absence of local codes, with
the National Electrical Code ANSI/NFPA 70 (latest edition) and Canadian Electrical Code, CSA C22.1.
Caution
Label all wires before disconnecting when servicing controls. Wiring errors can cause improper and
dangerous operation.
Warning
Electrical Grounding Instructions. This appliance is equipped with a three-prong (grounding) plug for your
protection against shock hazard and should be plugged into a properly grounded three prong receptacle.
DO NOT CUT OR REMOVE THE GROUNDING PRONG FROM THIS PLUG.
Always verify operation after servicing.

Gas Connection.

1. The gas line must be installed in accordance with all local codes, if any; if not, follow ANSI 223.1 and the
requirements listed below.
2. Verify that the gas type is correct for the fireplace insert by looking at the rating plate that is attached to the
control area of the appliance, adjacent to the control valve. Note: The fireplace insert is shipped from the
factory equipped to burn the fuel listed on the rating plate. Fuel conversion in the field is not allowed.
3. The gas inlet is located on the bottom left side of the appliance. Connection should now be made from the
gas supply line to the inlet flex connector on the fireplace. Use only a qualified gas installer to make the
connection.
4. The fireplace is shipped from the factory with a 1/2" female flare fitting on the 3/8" flex connector.
5. The gas supply piping should have a separate gas shut-off valve and a 1/8 NPT plugged tapping upstream
of the valve. We recommend installing a shut-off valve between the gas supply line where it penetrates the
wall / fireplace the flex on the fireplace insert. This will allow gas to be shut-off to the fireplace by simply
removing the fireplace surround to gain access to the shut-off valve.
6. The fireplace and its inlet regulator and main burner 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 (3.5kPa).
7. The fireplace must be isolated from the gas supply piping system by closing the gas shut-off valve during
any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psi (3.5kPa).
After the gas supply has been connected, use a commercial gas leak detector or apply a soapy water
solution to all the fittings to check for gas leaks. Never use a flame to test for
If the factory built fireplace has no gas access hole(s) provided, an access hole of 1.5" (37.5mm) or less
may be drilled through the lower sides, or bottom of the firebox in a proper workmanship like manner.
This access hole must be plugged with non-combustible insulation after the gas supply line has been
installed.
