1.4 GENERAL SAFETY

 Maintain adequate clearances around air openings into the combustion chamber.
 Maintain adequate accessibility clearances for servicing and proper operation.
 This appliance shall not be connected to chimney flue serving a separate solid-fuel burning

appliance.

 The appliance area must be kept clear and free from combustible materials, gasoline and other

flammable liquids and vapors.

 The flow of combustion and ventilation air shall not be obstructed.
 The combustion air supply shall be in the same pressure zone as the drafthood relief opening

on an appliance equipped with a drafthood or as the vent outlet on an appliance not equipped
with a drafthood.

 Do not use this appliance if any part has been under water. Immediately call a qualified

service technician to inspect the appliance and to replace any part of the control system and
any gas control which has been under water.

Due to high temperatures, the appliance should be located out of traffic and away from furniture
and draperies.
Children and adults should be alerted to the hazards of high surface temperature and should stay
away to avoid burns or clothing ignition.

Clothing or other flammable material should not be placed on or near the appliance.
Any safety screen or guard removed for servicing an appliance must be replaced prior to operating
the appliance.
Installation and repair should be done by a qualified service person. The appliance should be
inspected before use and at least annually by a professional service person. More frequent
cleaning may be required due to excessive lint from carpeting, bedding material, et cetera. It is
imperative that control compartments, burners and circulating air passageways of the appliance be
kept clean.

3.0 INSTALLATION

3.1 INSTALLATION & SAFETY NOTES

Read all instructions before starting installation and follow them carefully during installation to ensure
maximum benefit and safety. Failure to follow these instructions will void your warranty and may
present a fire hazard. See the warranty at the back of this manual for disclaimers regarding improper
installation. This direct vent fireplace and it’s components are tested and safe when installed in
accordance with this installation manual.

WARNING: Do not connect 120 VAC to the gas control valve or it’s wiring, as this
will damage the valve.

3.2 UNPACKING

Please check the appliance carefully for any damaged or missing components (specifically check the
glass condition). Report any problems to your dealer within 30 days of purchase.

3.3 INSTALLATION

For satisfactory results it is necessary to plan certain aspects of the installation prior to the
appliance’s final positioning. These include the vent system, the gas piping, and the fans wiring.
Combustible surfaces such as the hearth, mantle, and facing must also be planned for. Be sure to
leave adequate clearance for servicing and proper operation.

NOTE: All Installations Require Venting.

**The mantel placement chart on the previous page illustrates the allowable mantel sizes and
placements. The 1” incremental grid can be used to determine the allowable mantel size based on
the elevation above the units upper trim.

When using paint or lacquer to finish the mantel, such paint or lacquer must be heat resistant
(up to 250º F) to prevent discolorations.

Page 12 of 80

3.3.2 GAS LINE INSTALLATION

 Install supply line using any piping approved for your installation meeting CAN/CGA 6.10, AA 3,

ANSI Z21.24 or Z21.45. A qualified gas fitter should install the gas line in accordance with all
local building codes. If codes permit, coiled copper tubing may be used for gas supply.

 Pressure taps are provided on the gas control fo r test gauge connections to measure the manifold

and inlet pressures (see Lighting Instructions).

 This appliance must be isolated from the gas supply piping system by closing its individual manual

shut off valve during any pressure testing of the gas supply piping system at test pressures equal
to or less than 1/2 psig (3.45 kPa).

 The appliance and its individual shut off valve must be disconnected from the gas supply piping

system during any pressure testing of the system at test pressures in excess of 1/2 psig (3.45

kPa).
 Install the gas line as follows:
The appliance shall be installed with a manual shut off ball valve and additional pressure

regulator to bring line pressure down to 14” w.c..

Upon initial firing check manifold pressure at pressure tap located on the front control panel
(see Lighting Instructions in section 2.1).

WARNING: Do not use an open flame to test for gas leaks.

3.3.3 THERMOSTAT, WALL SWITCH OR DIGITAL ON/OFF REMOTE INSTALLATION

The burner control knob is located in the control compartment at the bottom of the unit. For your
convenience, the unit can also be operated by a thermostat, a digital on/off remote or a wall switch
control. Millivolt thermostats are available from any authorized Inca Metal Cutting dealer. Bedroom
installations require the use of a wall thermostat. Note: Thermostats are not allowed in the United
States.

NOTE: The thermostat, digital on/off remote or wall switch MUST be rated for
millivolt use. Minimize splicing in all millivolt wiring & crimp all unavoidable splices.

Thermostat, Digital On/Off Remote or Wall Switch Installation

Mount the thermostat, digital on/off remote or wall switch in the desired location and run “two
conductor thermostat wire” to the unit’s lower right hand corner, close to the gas supply line.

1. Purchase “two conductor thermostat wire”, which is not provided, at any local supplier. The

gauge of thermostat wire will determine the maximum wire length and distance at which to locate
the thermostat, digital on/off remote or wall switch. See Table 1 and the information packaged
with thermostat. Be aware that as the length of wire increases, the probability of adequate
operating voltage decreases.

18 1.0 40 12.2
16 1.3 64 19.5
14 1.6 100 30.5

2) After the unit is installed and the gas line hooked up, crimp a fork connector to each wire and

attach them to the TH/TP and TH screws located on the valve.

3) Check tests can be performed on the valve by using the trouble-shooting guide, Section 5.0.

4) This switch may be connected in parallel with a thermostat, digital on/off remote or wall switch

(see Figure 4).

3.3.4 Direct Vent Information

The unit must be connected to listed 2-ply aluminium venting, 4” flex vent on the exhaust side and
listed 7” flex vent on the air intake side or can be used with Security Venting or Simpson Dura-Vent 4”
x 6-5/8” with the use of Simpson Dura-Vent adapters part #’s 0924N3 & P574. Install the vent
components according to the manufacturer's instructions being sure to use spacers (see Figure 5)
every 5’ to ensure correct spacing is maintained between air intake and exhaust. Slope horizontal
pipe at least 1/4" (6 mm) rise per foot of horizontal run. Allow 1" (25 mm) clearance to the vent.
Refer to the graph for allowable vent configurations. Be sure to ensure that termination area allows
enough room for adequate combustion and ventilation air and that the flow of combustion and
ventilation air is not obstructed.

Note: If at any time the vent-air intake piping is dismantled, use the vent manufacturer’s

instructions and the sealing instructions for reassembly.
