1. Oil Fired Boilers

Boiler is low pressure, sectional cast iron constructed

and tested for maximum working pressure of 65 psi in

accordance with A.S.M.E. (American Society of Mechanical

Engineers) Section IV Standards for cast iron heating

boilers. Capacity rated in accordance with AHRI (Hydronics

Institute).

Boiler is pressure fired natural draft (chimney vented)

oil fired hot water boiler comprised of cast iron sections,

available with 4, 5, 6 or 7 sections. Sections are held

together by metal push nipples and threaded rods.

4, 5 and 6 section boilers may be field equipped for direct

vent installations with use of direct vent burner and venting

kits. Direct vent instructions are covered in a separate

supplemental instruction document included with direct

vent venting kit.

Boiler models are capable of firing #2 fuel oil from 0.75

gph up to 1.80 gph.

Boilers include -

• Limit, 220° F maximum, operating control with integral

low water cut off

• Temperature and pressure gauge
•

30 psi relief valve

•

Drain valve

WARNING

Installations of boilers and venting shall be done

by a qualified expert and in accordance with this

manual. Installing or venting a boiler or any other

oil appliance with improper methods or materials

could result in serious injury or death due to fire

or to asphyxiation from poisonous gases such as

carbon monoxide which is odorless and invisible.
