General Requirements

1. Chimney MUST be a 8” Class "A" chimney. Do Not Use chimney smaller than 8”.

2. INSTALLATION MUST BE DONE BY A LICENSED HVAC/HYDRONIC CONTRACTOR FAMILIAR WITH ALL STATE

AND LOCAL CODES. Safe operation of any gravity vented heating appliance requires a proper air make-up system

to prevent the heater exhaust gases from being drawn into the building. These gases could cause death, serious

injury, and/or property damage. Exhaust fans, paint booths may cause draft problems.

3. Never vent this boiler into another heating appliances chimney. Never vent into ‘Class B” chimney. Gas boilers use

“Class B” chimney, it is rated for a much lower temperature than is required for your waste oil boiler. This

boiler must have its own separate “Class A” chimney.

4. Inspect and maintain the chimney on an annual basis.

5. Install a U.L. listed barometric damper in the chimney. Do not reduce or enlarge the vent pipe.

6. Position the draft control as shown. Chimney angle gate pins must be horizontal for proper operation.

7. Keep the barometric draft control at least 24” from the boiler.

NOTE: Barometric

Damper may be mount-

ed horizontally or verti-

cally. Angle gate pins
