Burnham ES2 manual Provide Combustion Air, Connect Venting

3. Provide Combustion Air

INSUFFICIENT COMBUSTION AIR SUPPLY may result in the production and

release of deadly carbon monoxide (CO) into the home which can cause severe personal injury or death.

Like all fuel-burning appliances, boilers need air to operate reliably and safely.

Provide combustion air using the instructions in Appendix A—Combustion Air.

4. Connect Venting

IMPROPER VENTING may result in property damage and the release of flue

gases which contain deadly carbon monoxide (CO) into the home, which can cause severe personal injury, death or substantial property damage.

The vent system shall be designed and constructed in accordance with NFPA 54 and applicable local codes to develop a positive flow adequate to convey flue or vent gases to the outdoors, while ensuring that flue gases do not cool prematurely.

Observe all general venting guidelines provided in Appendix B—Venting.Additionally:

1.This appliance shall be vented into a listed gas vent, masonry, metal, or factory- built chimney as required by NFPA 54 and applicable local codes for Category I appliances. If venting this appliance into a masonry chimney, the chimney must be lined with a listed chimney lining system

(i.e. Type B gas vent or flexible metal) as required by NFPA 54 and applicable local codes. Clay flue lined masonry chimneys do not meet the venting requirements for this appliance.

2.Attach the vent damper with three sheetmetal screws around the perimeter of the flue collar (Figure 4-a), oriented so that the position indicator is visible. The vent damper may also be mounted anywhere between the flue outlet and the chimney within reach of the electrical harness.

3.Vent connector shall be double-wall insulated gas vent as supplied with this boiler or Type B (double-wall) gas vent only. Using sheetmetal screws, attach the vent connector between the vent damper and the vertical chimney (Figure 4-b). Do not exceed the maximum vent connector length in Table 4.1.
