INNOVATIVE HEARTH PRODUCTS • POWER VENT DV GAS FIREPLACES (DRT6340TYN AND DRT6345TYN) • INSTALLATION INSTRUCTIONS
These appliances are listed by Intertek for
installation in bedrooms and manufactured
(mobile) homes.
Installation must conform to local codes. In the
absence of local codes, installation must comply
with the current National Fuel Gas Code, ANSI
Z223.1/NFPA 54 (in Canada, the current CAN/
CGA-B149.1 installation code).
The appliance, when installed, must be electri-
cally grounded in accordance with local codes
or, in the absence of local codes, with the
National Electrical Code, ANSI/NFPA 70 - latest
edition, or the Canadian Electrical Code, CSA
C22.1 - latest edition.
Provide adequate clearances around air open-
ings and adequate accessibility clearance for
service and proper operation. Never obstruct
the front openings of the appliance.
These appliances are designed to operate on
natural gas. The use of other fuels or combina-
tion of fuels will degrade the performance of
this system and may be dangerous.
These appliances must not be connected to a
f i r e - p a r t s . c o m
chimney or flue serving a separate solid fuel
burning appliance.
These electronic appliances are remotely con-
trolled and feature an electronic intermittent
pilot ignition system. External electrical power
is required to operate these units.
These electronic models come standard with a
remotely-modulated gas valve; flame appear-
ance and heat output cannot be controlled at the
gas valve. The BTU Input for these appliances
is shown in Table 1.

Test gauge connections are provided on the front
of the gas control valve; identified IN for the inlet
and OUT for the manifold side (see Figure 1).
The appliance and its appliance main gas
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 equipment
shutoff valve during any pressure testing of
the gas supply piping system at test pres-
sures equal to or less than 1/2 psi (3.5 kPa).

PURGE CYCLE
This is a power vented fireplace that
requires household electrical power
to operate. It will not operate during
a power failure. When the fireplace
is turned off, the exhaust blower will
continue to operate for approximately
fifteen (15) seconds after shutdown
to expel the exhaust gases from the
venting system.

Orifice Sizes - Sea Level To High Altitude
13.0" WC
These appliances are tested and approved for
(3.23 kPa)
installation at elevations of 0 - 4500 ft (0 - 1370
m) above sea level, using the standard burner
orifice sizes (marked with an "*" in Table 4).
For elevations above 4500 ft, contact your gas
supplier or qualified service technician.
Deration - At higher elevations, the amount

by either:
(2.49 kPa)
• Using gas that has been derated by the gas
company.
• Changing the burner orifice to a smaller size
as regulated by the local Authorities Having
Jurisdiction and by the (USA) National Fuel
Gas Code NFPA 54/ANSI Z223.1 - latest
edition, or in Canada, the CAN/CGA-B149.1
code - latest edition.
Install the appliance according to the regulations
of the local authorities having jurisdiction, and
the (USA) National Fuel Gas Code NFPA 54 /
ANSI Z223.1 - latest edition,
or (Canada) CAN/CGA-B149.1 - latest edition.
