SECTION I: PRODUCT DESCRIPTION, SPECIFICATION
AND DIMENSIONAL DATA
The V8H Series boiler is a cast iron oil-fired water boiler
designed for closed forced circulation heating systems or a
low pressure steam boiler designed for use in closed heating
steam systems. This boiler must be vented by natural draft
into a fireclay tile-lined masonry chimney or chimney
constructed from type L vent or a factory built chimney
that complies with the type HT requirements of UL03. An
adequate supply of air for combustion, ventilation and
dilution of flue gases must be available in the boiler room.
Water Boilers
The V8H Series water boiler uses an Intelligent Oil
Boiler Control (boiler control). The boiler control
replaces the traditional electronic aquastat and
circulator relays and adds energy saving thermal purge
features. Energy is saved by starting the circulator and
delaying the burner start when there is residual heat
available in the boiler. A Warm Start Intelligent Oil
Boiler Control (Warm Start Boiler Control) is included
with a tankless heater option to generate domestic hot
water.
Steam Boilers
The V8H Series steam boiler uses a L404F Pressure
Limit and Low Water Cut-off. This boiler has indirect
domestic water heater connections to generate domestic
hot water. Optionally, this boiler may include a L4006
Temperature Limit and a tankless heater to generate
domestic hot water.
