PLANNING YOUR VENTING INSTALLATION
INSTALLATION
IMPORTANT
Read all instructions carefully before starting
the installation. Failure to follow these instruc-
tions may create a fire or other safety hazard,
and will void the warranty. Be sure to check the
venting and clearance to combustible require-
ments on pages 6 to 10. Consult your local
building codes before beginning installation.
The location of the termination cap must con-
form to the requirements in the Exterior Vent
Terminal Locations diagram on page 7.
VENTING
INSTALLATION
PRECAUTIONS
The Regency Direct Vent System and the Ver-
tical Termination with the Co-linear Flex System
are engineered products that have been de-
signed and tested for use with the U37-NG, and
U37-LP. The Regency warranty will be voided
and serious fire, health or other safety hazards
may result from any of the following actions:
1) Installation of any damaged Direct Vent
component
2) Unauthorized modification of the Direct Vent
System
3) Installation of any component part not man-
ufactured or approved by Regency Indus-
tries Ltd.
4) Installation other than as instructed by Re-
gency Industries Ltd.
Warning: Always maintain required
clearances (air spaces) to nearby
combustibles to prevent a fire haz-
ard. Do not fill air spaces with insu-
lation.
The minimum clearance requirements between
the outer wall of the vent pipe and nearby
combustible surfaces is 1-1/4 inch. Be sure to
check the vent termination clearance require-
ments from decks, windows, soffits, gas reg-
ulators, air supply inlets and public walkways
as specified on page 7 and in your local building
codes.
The gas appliance and vent system
must be vented directly to the out-
side of the building, and never be
attached to a chimney serving a
separate solid fuel or gas-burning
appliance.
Each direct vent gas appliance must use its
own separate vent system. Common vent sys-
tems are prohibited.
SAFETY
PRECAUTIONS FOR
THE INSTALLER
1) Wear gloves and safety glasses for pro-
tection.
2) Exercise extreme caution when using lad-
ders or on roof tops.
3) Be aware of electrical wiring locations in
walls and ceilings.
See page 7 for Exterior Vent Termination
requirements. .
When planning your installation, it will be nec-
essary to select the proper length of vent pipe
for your particular requirements. Determine the
minimum clearance to combustibles from the
rear of the unit to the wall. It is also important to
note the wall thickness. Before cutting the vent
hole through the wall ensure that ALL vent and
termination clearances (see page 7) will be met.
*If this is an outside corner, the minimum distance between the vent and the outside corner
is 12" (30cm). See "F" on the diagram on page 7.
NOTE: Ensure compliance with the outside vent terminal location before cutting hole as both dimensions must be met.
For corner installation, Restrictor must
be set at 1-1/4" open.
For straight rear installation, Restric-
tor must be set at 1-1/8" open.
