U20/E21 Gas Insert Zero Clearance Kit

INSTALLATION

GENERAL INFORMATION

This kit consists of factory built parts that require minimal
assembly to form the Zero Clearance box for the U20/E21
Gas Insert. The Zero Clearance box can then be fixed into a
framed combustible construction, and a standard "B-vent"
installed on the assembly for the required venting. The
insert can be installed later. The faceplate will normally
overlap on top of the finished wall. Using Kit# 530-936 you
can convert the U20/E21 Gas Insert models into highly
efficient heat producing Zero Clearance Fireplaces.

Included with Kit:

1 Main Body Assembly (5 pieces)
1 Faceplate Top Insulation
1 Zero Clearance Top Louver Assembly

Sold Separately:

(Rq) 1 402-918 Faceplate 40-1/4"W x 26-1/4"H

(Rq) 1 532-926 4"(102mm) Hearth Trim

CLEARANCES TO COMBUSTIBLES

The clearances for the Zero Clearance Kit are 0" to combustibles (back, side and floor) but when planning your
installation review the clearances required for the Insert (see below) after it is installed in the Zero Clearance Kit.

Clearances to Combustibles for Insert

The minimum clearance from the side of the appliance
to a combustible side wall is 9 inches (229mm). See the
"Mantel Clearances" chart (Diagram 2) for the minimum
clearance from the bottom of the Top Faceplate to a
combustible mantel. The minimum height from the
bottom of the Top Faceplate to the ceiling is 36 inches
(914mm). See diagram 1.

Diagram 2

Diagram 1

The Zero Clearance Kit
must be installed on a
flat, solid, continuous
surface (e.g. wood,
metal, concrete). This
may be the floor, or
raised up on a platform
to enhance its visual
impact.

NOTE: The specified '0' inch floor clearance means that
the top surface of the flooring material, i.e. carpeting, tile,
etc., must not extend above the bottom edge of the 4"
Hearth Trim.

4

Diagram 2: Mantel can be installed anywhere in the
shaded area or higher. Use the grid to determine
height and depth of mantle.

Example: a 6" deep mantle must be 9" above the
bottom of the top faceplate.

Note: A non-combustible mantel may be installed
at a lower height if the framing is made of metal studs
covered with a non-combustible board.

Note: Ensure the paint that is used on the mantel and the
facing is "heat resistant" or the paint may discolour.

U20/E21 Gas Insert Zero Clearance Kit

LOCATING YOUR U20/E21 FIREPLACE

Due to high temperatures the Insert should be located out of traffic and
away from furniture and draperies. Provide a minimum of 48" (1220mm)
front clearance to the unit.

Clearance box to the same
degree as the rest of the

INSTALLATION

VENTING

1) This fireplace must be vented with a 4" (100mm)

diameter Class “B” vent. The installation of the
venting system must conform and be in accordance
with the natural gas installation code CAN/CGA ­B149 (Canada), ANSI Z223.1 (U.S.A.), AG 601
(Australia), and NZS 5261 (New Zealand). Minimum
chimney height from base of fireplace must be at
least 12 feet (3.7m).

2) Masonry Chimney Installation:

This application can be connected to a masonry
chimney flue. Make sure the masonry chimney is
clean and in good working order. When an existing
masonry chimney is unlined and local experience
indicates that gas condensation may be a problem
or if local codes dictate, an approved liner should be
installed. Use “B” Vent to bridge the gap between the
fireplace and the masonry chimney. To ensure
proper flue sizing and operation it is recommended
that the masonry chimney be lined with an approved
aluminium chimney liner of the same diameter as the
“B” Vent. Make sure connection between “B” Vent
and masonry is completely sealed. Flue pipe exposed
to cold air should be insulated in a chase. If
condensation occurs, a trap should be installed at
bottom of flue.

Use a maximum of two offsets; four 45o elbows, or two
90o elbows for example. Slope horizontal pipe at least
1/4" (6.4 mm) rise per foot of run. Horizontal runs
should not exceed the vertical rise. Keep horizontal
runs to a minimum. See chart below.

NOTE: Cold Climate Installation

When this appliance is to be installed against a non­insulated wall or in a chase, fibreglass insulation should
be installed around the body of the fireplace.

Note: The draft hood must be installed parallel to the

fireplace opening, as shown below. See
Instructions in U20/E21 Installation Manual.

Install stove insert as per U20/E21 Installation Manual,
see also page 8.

INSTALLATION

INSERT INSTALLATION

1) Insert the U20/E21 Zero Clearance box into desired

location and frame according to the instructions on
page 5.

2) Run required gas and electrical connections to the
Zero Clearance box, both are located on the left hand
side of the U20/E21 Insert. See "Gas Supply Line" on
page 9 and "Electrical Supply" on page 9.

3) Remove the screw holding the draft hood slide plate
on the U20/E21 unit and remove.

4) Attach the draft hood slide plate to the flue collar
assembly with three sheet metal screws.

NOTE: ensure that when the draft hood slide plate
is screwed in that it is the same height as the draft
hood guides or it will not slide into position.

5) Slide the gas insert in all the way back using the draft
hood guides. Draft hood must be in original position
and replace the screw holding the draft hood.

6) Make the final gas and electrical connections as per
the Insert Instruction manual. Use the gas line cover
plate that is included with the Zero Clearance box.

7) Assemble the Faceplate and Trim and the 4" Hearth
Trim to the U20/E21 zero clearance box as per the
instructions on page 10.

8) Attach the Top louver assembly to the Zero Clearance
Kit by placing the louver clamps into the square hole
on the louver holding brackets as per the instructions
on page 11.

Note: Do not operate unit if draft hood is not fastened

in original position.

INSTALLATION

OPTIONAL OUTSIDE COMBUSTION AIR SUPPL Y INST ALLA TION

A 4" (100 mm) dia. aluminum flex pipe or equivalent may
be installed from the outside (with a proper exterior
cover) to the Zero Clearance cabinet. There is an outside
hole provided on the rear wall of the kit. This will provide
adequate outside combustion air supply to the heater.

GAS SUPPLY LINE

An authorized service person should install the gas line in accordance with all local building codes. If codes permit,
flex gas line or coiled copper tubing may be used as gas supply line. The suggested way to install the gas supply
line is as follows: run 1/2" (9.5 mm) NPT gas line to the left side of the framed opening. (See U20/E21 installation
instructions for additional information).

FACEPLATE & TRIM

INSTALLATION

1) Lay the faceplate panels flat, facedown on something

soft so they don't scratch.

2) a) Take the top faceplate and align the holes in it
with the holes in the side panels. Using the
screws provided, attach from the top of the panel
(holes in the top panel are slightly larger than the
holes in the side panel to facilitate easier
installation). See diagram 1.

b) 4"(102mm) Hearth Trim. Attach the Hearth Trim

to the bottom of the faceplate side panels with
the screws provided. See diagram 1.

Hint: Don't tighten the screws down completely at
this point, do a trial fit to the unit. Make any
necessary adjustments and when it fits properly
then tighten down the screws.

3) Using the trim clips provided, join the left side trim

(with the ON/OFF switch) to the top trim. See
diagram 2. Connect the right side trim to the top trim.

Faceplate Assembly

Diagram 1

4) Place the trim on the assembled faceplate panels,

aligning the wire connections from the switches with
the notch on the left side panel.

5) Connect the fan switch wires by taking the black and

red wires with the male ends (in the grey harness)
and connect them with the 2 wire connectors from
the fan speed control.

6) Connect the ON/OFF switch wires by taking the

black and red wires with the female ends and
connect them to the ON/OFF switch.

7) Install these wires in the clips on the left faceplate

to ensure they don't touch the insert. See diagram 3.

8) The power cord should be run behind the faceplate

panel from the U20/E21 to electrical outlet box.

9) Place top insulation in behind the top faceplate as in

FINISHED FACING

NOTES

Install finished facing surface
of 1/2"(13mm) thickness on
framing. Drywall 1/2" (13 mm)
thick can extend flush with the
appliance on all three sides of
the front face. The height at
which the mantle must be
installed above the top louver
depends on the depth of the
mantle. If the mantle is to be
painted, use a heat resistant
paint to prevent discolouration.
