INSTALLATION COMMENT: We recommend that sufficient space be
provided (minimum 20 inches/500 mm) on each side of the heater to ser-
vice the equipment area. In case this is not possible, provisions must be
made to pull out the heater for service.
FLOOR PROTECTION: A non-combustible material, extending a mini-
mum of 6 inches (150 mm) in front of the heater is required.
3. Electrical Requirements
1. This heater is an electrical appliance and requires 120 Volts, 60 cycle, 3
Amp of electrical power.
2. This heater comes with a 5 ft. (1.5 M) long, grounded, electrical cord
suitable to plug into any standard residential electrical outlet. The
electrical outlet must be grounded.
3. When installed in a mobile home, the heater must be grounded to the
steel chassis of the home (unless this is not required by local code).
4. Venting System
Before proceeding with the installation, the following sections should be reviewed:
Section 4 : Venting System
Section 5 : Location of the Heater
Section 6 : Typical Installation Configurations
4.1 Exhaust Vent Pipe Requirements
KOZI
pellet stoves have a negative pressure burn chamber. A high-pressure, radial
blade fan pulls the air out of the burn chamber creating negative pressure (vacuum)
inside the burn chamber. The air from outside the stove then rushes through the intake
air tube, burn pot stand and burn pot to fill this vacuum. As this air passes through the
burn pot it is used to burn the pellets. A proper size ULC/UL listed type PL or L venting
should be used to provide the least resistance for movement of the combustion air.
This
KOZI
pellet burner is certified for 3 inch exhaust venting. 3 inch venting is quite
sufficient for most direct vent installations. However, installations with several elbows,
long horizontal and/or vertical runs may add excessive resistance against the flow of air,
which reduces the volume of air movement and creates burn problems. Use of 4 inch
venting will reduce this resistance. A simple technique called ‘EQUIVALENT VENT
LENGTH (EVL)’ can be used to determine whether 3 or 4 inch vent pipe should be used.
