LENNOX HEARTH PRODUCTS • SIGNATURE® SERIES DIRECT-VENT GAS FIREPLACES • ENVY/ENVY CD 35/40/45 • CARE AND OPERATIONS
INTRODUCTION
The fireplace models covered in this
manual are direct-vent sealed combustion
gas fireplace heaters designed for
residential application. These direct-vent
appliances operate with the combustion
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, co-axial
(intake/exhaust) vent system.
Electronic appliances are designed to
operate on natural or propane gas. An
electronic intermittent pilot ignition system
provides safe, efficient operation. External
electrical power is required to operate
these units. In the event of a power outage,
four (4) AA batteries provide backup power
for appliance operation (excluding blower).
These appliances comply with National
Safety Standards and are tested and listed
by ETL/Intertek. (Report No. G100513653
PRT-001) to ANSI Z21.88 (in Canada,
CSA-2.33), and CAN/CGA-2.17-M91 in both
USA and Canada, as vented gas fireplace
heaters. These appliances are listed by ETL/
Intertek for installation in bedrooms and
manufactured homes.
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—latest edition (In Canada,
the current CAN/CSA-B149.1 installation
code). The appliance, when installed,
must be electrically grounded and wired
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
openings and adequate accessibility clearance
for service and proper operation. Never obstruct
the front or back openings of the appliance.
These appliances are designed to operate on
natural or propane gas only. The use of other
fuels or combination of fuels will degrade
the performance of this system and may be
dangerous. It is advisable to have an alternate
primary heat source when installed in a dwelling.
These appliances must not be connected to
a chimney or flue serving a separate solid
fuel burning appliance.
The vent termination is hot while in
operation and for a period of time
following the use of the fireplace. To
prevent contact with hot surfaces, we
recommend the use of a termination
guard. See Page 20 for ordering
information.
These fireplaces are designed as
supplemental heaters. Therefore, it is
advisable to have an alternate primary
heat source when installed in a dwelling.
These appliances must not be connected
to a chimney or flue serving a separate
6
solid fuel burning appliance.
INSTALLATION, SERVICE,
AND MAINTENANCE
NOTE: Improper installation, adjustment,
alteration, service, or maintenance can
cause injury or property damage. Refer to
this manual. For assistance or additional
information, consult a qualified installer,
service agency or the gas supplier.
Only trim kit(s) supplied by the
manufacturer shall be used in the
installation of this appliance. Draft relief
openings must not be covered or blocked.
These appliances must not be connected
to a chimney or flue serving a separate
solid fuel burning appliance.
Any change to this appliance and/or its
operating controls is dangerous. Improper
installation or use of this appliance
can cause serious injury or death
from fire, burns, explosion or carbon
monoxide poisoning.
Early signs of carbon monoxide poisoning
are similar to the flu with headaches,
dizziness and/or nausea. If you have
these signs, obtain fresh air immediately.
Turn off the gas supply to the appliance
and have it serviced by a qualified
professional, as it may not be operating
correctly. Some people are more affected
by carbon monoxide than others, including
pregnant women, people with heart or
lung disease or anemia, those under the
influence of alcohol, and those at high
altitudes.
Turn off gas and electrical power to the
fireplace and allow it to cool before
cleaning or servicing the appliance.
WARRANTY
Failure to comply with the installation and
operating instructions provided will result
in an improperly installed and operating
appliance, voiding its warranty.
Do not attempt to alter or modify the
construction of the appliance or its
components. Any modification or alteration
may void the warranty, certification, and
listings of this unit.
DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
OPERATION
WARNING
Do not operate the fireplace if:
• The glass front is removed,
cracked, or broken
• The surround trim assembly
and screen are not installed
These fireplaces are vented gas appliances.
Do not burn wood or other material in these
appliances.
This appliance is only for use with the
type of gas indicated on rating plate. This
appliance is not convertible for use with
other gases, unless a certified kit is used.
These appliances are designed to operate
on natural gas or propane gas only. The use
of other fuels or combinations of fuels will
degrade the performance of this system and
may be dangerous.
Provide adequate clearances around
air openings and adequate accessibility
clearance for service and proper operation.
Never obstruct the front openings of the
appliance.
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 that has
been under water.

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
These appliances are tested and approved
for installation at elevations of 0–4500 ft
(0–1372 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 of BTU fuel
value delivered must be reduced by either:
• 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/CSA-B149.1 codes—

Burn-in Period
During the first few times this appliance
is operated, there will be some odor due
to the curing of the paint and burning off
of lubricants used in the manufacturing
process. Depending on usage, the burn-in
period may take a few hours or a few days.
NOTE: Ventilate the house during the curing
process. The resulting odor and haze may
set off a smoke detector. Do not operate the
blower during the burn-in period.
A white film may develop on the glass
front during the first few fires as part of the
curing process. The glass should be kept
clean during the first two weeks of use to
prevent the film from baking on—making it
very difficult to remove (Cleaning the glass
door on Page 11)
NOTE: Flame breadth, height and width will
diminish 4% for every 1,000 feet of altitude.
