Locating the Vent Opening. Cozy Hi-Efficient Direct Vent

INSTALLATION

ATTENTION: ALL CANADIAN CONTRACTORS/INSTALLERS: Before installing this heater into a multi-family hi-rise exceeding four stories, contact the local building code inspector to verify the building construction complies with the Progressive Collapse requirements as listed in the National Building Code of Canada 2005.

!

WARNING: FAILURE TO FOLLOW THESE INSTRUCTIONS CAREFULLY COULD RESULT IN POOR

PERFORMANCE, PROPERTY DAMAGE, PERSONAL INJURY, OR DEATH.

Step 1.

LOCATE VENT OPENING

(Requires 3-1/2” diameter wall opening).

a) Select area on wall where heater will be installed. Using template (packed with heater) mark shaded area where hole can be cut and to locate the wall brackets.

(See

Figure 4).

b) Locate studs on each side of this area.

c) Mark location for 3-1/2” diameter hole between studs.

Hole should be offset to miss studs.

(See Figure 4).

d) Check outside wall at this location for proper clearances around vent cap. (See Figure 1).

e) Cut vent openings into both the inside and outside walls, being sure to maintain level across both openings.

Step 2.

ROUGH-IN GAS SUPPLY (See Figure 5)

Install at least 3/8” gas supply line. Contact local gas supplier if any questions.

FIG. 5

Install a drip leg in gas supply line immediately upstream from the gas connection to heater (see local codes), and provide a 1/8” N.P.T. plugged tapping, accessible for test gauge connection and an individual manual shut off valve accessible within room where heater is installed. (See Figure 5 ). The heater and its individual shut off 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 psig (3.5 Pa). The heater must be isolated from the gas supply piping system by closing its individual manual shut off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 Pa). Test all connections for leaks using a soapy solution. NEVER USE AN OPEN FLAME TO

TEST FOR LEAKS.
