VENTING
INSTALLATION
PRECAUTIONS
The Regency® Direct Vent System and the
Vertical Termination with the Co-linear Flex
System are engineered products that have
been designed and tested for use with the
U37-NG1, and U37-LP1. The Regency® warranty will be voided and serious fi re, health or
other safety hazards may result from any of the
following actions:
1) Installation of any damaged Direct Vent
component
2) Unauthorized modifi cation of the Direct Vent
System
3) Installation of any component part not
manufactured or approved by Regency®
Industries Ltd.
4) Installation other than as instructed by
Regency® Industries Ltd.
Warning: Always maintain required
clearances (air spaces) to nearby combustibles to prevent a fi re hazard. Do
not fi ll air spaces with insulation.
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 requirements
from decks, windows, soffi ts, gas regulators, air
supply inlets and public walkways as specifi ed
in the "Exterior Vent Terminal Locations" section
and in your local building codes.
The gas appliance and vent system
must be vented directly to the outside
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 systems
are prohibited.
SAFETY PRECAUTIONS
FOR THE INSTALLER
1) Wear gloves and safety glasses for protec-
tion.
2) Exercise extreme caution when using lad-
ders or on roof tops.
3) Be aware of electrical wiring locations in
walls and ceilings.
PLANNING YOUR VENTING INSTALLATION
See the "Exterior Vent Terminal Locations"
section for the requirements. .
When planning your installation, it will be necessary 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 the "Exterior Vent
Terminal Locations" section) will be met.
NOTE: Ensure compliance with the outside vent terminal location before cutting hole as both dimensions must 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 in the "Exterior Vent Terminal Locations" section.
For corner installation, Restrictor must
be set at 1-1/4" open.
For straight rear installation, Restrictor
must be set at 1-1/8" open.
