1 EG, PEG, EGH GAS-FIRED BOILERS — SERIES 4 — BOILER MANUAL

Installation (continued)

Jacket installation (Factory installed on PEG boilers)

1.Remove the proper knockout discs from panels as shown in tapping table, page 6.

Tankless and storage heater knockouts must be removed for EG and EGH boilers with optional tankless heaters prior to jacket installation.

2. Follow Jacket Instructions in jacket carton.

Spill switch installation

On EG 30-75 boilers only, fasten spill switch to draft hood as shown on page 22, Drawing Ref. Letter “K”. Connect wires as shown in Control Supplement.

Damper installation

If damper will be installed, see Control Supplement for information.

Draft hood installation

Attach draft hood to flue collector hood using #10 x 1/2" sheet metal screws provided. Use boiler cement furnished to provide gas tight seal.

Failure to maintain gas-tight seal can cause flue gas spillage and carbon monoxide emissions, resulting in severe personal injury or death.

Do not alter boiler draft hood or place any obstruction or non-approved damper in the breeching or vent system. A.G.A. and C.S.A. certifications will become void. Flue gas spillage and carbon monoxide emissions will occur causing severe personal injury or death.

Breeching erection

Connect from draft hood or damper outlet to chimney or vent with same size breeching. Where possible, vertical venting to the outside from draft hood or damper outlet will offer best performance. Where horizontal breeching is used, slope upward at least 1/4 inch per lineal foot toward chimney or vent and support with hangers to prevent sagging.

A vertical height of 3 feet to 5 feet of breeching before any elbow or horizontal breeching is recommended to reduce chances of flue gas spillage at draft hood on EGH-95 thru -125 boilers (not restricted on any EG or EGH-85). Long horizontal breechings, excessive numbers of elbows or tees, or other obstructions which restrict the flow of combustion gases should be avoided.

Breeching must not be connected to any portion of a mechanical draft system operating under positive pressure.
