INNOVATIVE HEARTH PRODUCTS • SEE-THROUGH POWER VENT DV GAS FIREPLACES (DRT63STYN) • INSTALLATION INSTRUCTIONS
GENERAL INFORMATION
The fireplace models covered in this manual
are direct-vent, sealed combustion gas fire-
places designed for residential application.
Direct-vent appliances operate with the com-
bustion chamber completely isolated from the
indoor environment.
All air for combustion is brought in from the
outside, and exhaust gases are vented through
the same direct-vent, coaxial (intake/exhaust)
vent system.
These appliances are designed to operate on
natural or propane gas (propane units are avail-
able as a field conversion only). The system
is switchable between standing and intermit-
tent pilot modes. External electrical power is
required to operate these units.
These models come standard with a remotely
modulated gas valve. The included transmitter
remotely controls flame appearance and heat
output (manual gas valve adjustment is not
possible).
These appliances comply with National Safety
Standards and are tested and listed by PFS
(Report No. F14-107) to ANSI Z21.88 (in
Canada, CSA-2.33), and CAN/CGA-2.17-M91
(CSA P4.1) in both USA and Canada, as vented
gas fireplace.
The installation must conform to local codes or,
in the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.1/NFPA 54 - lat-
est edition, or the Natural Gas and Propane
Installation Code, CAN/CSA-B149.1 - latest
edition. The appliance, when installed, must
be electrically 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.

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 13 on Page 39 ). The control valve has
a 3/8" (10 mm) NPT thread inlet and outlet side
of the valve.
These appliances must be isolated from
the gas supply piping system (by closing
their 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 (3.5 kPa).
These appliances and their individual
shut-off valves must be disconnected
from the gas supply piping system dur-
ing any pressure testing of that system
at pressures greater than 1/2 psig (3.5
kPa).

Orifice Sizes:
Sea Level to High Altitude
These appliances are tested and approved
for installations at elevations of 0–4500 feet
(0–1372 meters) above sea level using the
standard burner orifice sizes (see Table 14).
For higher elevations, contact your gas supplier
or qualified service technician.

Deration
At the time of installation, it must be deter-
mined if the appliance needs to be derated.
Contact your local gas supplier for deration
requirements for your area.
At higher elevations, the amount of BTU fuel
value delivered must be reduced by either using
gas that has been derated by the gas company
or by 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/CSA-B149.1 codes - latest
edition.
Burn-in Period
During the first few fires of this appliance there
will be some odor due to the curing of the
paint and burning off of lubricants used in the
manufacturing process. Depending on your
use, the burn-in period may take a few hours
or a few days.
KEEP YOUR HOUSE WELL VENTILATED
DURING THE CURING PROCESS. THE ODOR
AND HAZE EMITTED DURING THE CURING
PROCESS CAN BE QUITE NOTICEABLE AND
MAY SET OFF A SMOKE DETECTOR.
NOTICE:
A white film may develop
on the glass enclosure panel during
the first few fires as part of the burn-in
process.
The first few times you use the
fireplace, clean the glass after each use
(AFTER THE GLASS HAS COMPLETELY
COOLED); otherwise, the white film
will bake onto the glass and become
difficult to remove.
See glass cleaning instructions on
Page 43.
