DRT/DRC6300 Series Direct-Vent Gas Fireplaces
These electronic appliances are remotely
controlled and feature an electronic intermit-
tent pilot ignition system or standing pilot.
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 appli-
ances 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).
Propane tanks are at pressures that will cause
damage to valve components. Verify that the
tanks have step-down regulators to reduce the
pressure to safe levels.
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 pressures
equal to or less than 1/2 psi (3.5 kPa).

Orifice Sizes—Sea Level To High Altitude
(All Models)
These appliances are tested and approved
for installation at elevations of 0–4500 feet
(0–1372 meters) above sea level, using the
standard burner orifice sizes (marked with an
asterisk (*) in Table 4). For elevations above
4500 feet, contact your gas supplier or qualified
service technician.
Deration—At higher elevations, the amount
of BTU fuel value delivered must be reduced
by either:
Input (BTU/Hr)
• using gas that has been derated by the gas
company; or
• 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
codes—latest edition.
Install the appliance according to the regulations
of the local authorities having jurisdiction and,
in the USA, the National Fuel Gas Code NFPA
54 / ANSI Z223.1—latest edition or , in Canada,
the CAN/CGA-B149.1- latest edition.
NOTE: Flame appearance will diminish 4% per
thousand feet of altitude.
