• When communicating with outdoors by means of vertical ducts, each

opening shall have a free area of not less than one square inch per

FLUE GAS VENTING

In the absence of any local codes, regulations, or vent pipe or chimney

manufacturer's recommendations, for oil red equipment, follow the

suggestions below for designing and installing a venting system.

For these water heaters, it is recommended that an adequate chimney be

used for venting the ue gases. Type B, double wall, vent pipe should be

used as the vent connector pipe. However, where no chimney is available,

vent pipe may be used to construct a vent.

Where an existing chimney or vent is to be used, be sure that the chimney

or vent has adequate capacity for the number and sizes of appliances

being vented through it. Inspect the chimney or vent and remove all soot

or other obstructions which will retard free draft.

VENT CONNECTOR AND DRAFT REGULATOR

The chimney or vent connector diameter should be the same size as the

heater ue outlet, see Table 4. A minimum rise of 1/4" per foot (21mm/M)

of horizontal connector length must be maintained between the heater

and chimney opening, g. 6. The connector length should be kept as

short as possible.

* These models are factory supplied with a ue reducer which should

be installed on the top cover.

In venting systems where a continuous or intermittent back (positive) draft

is found to exist, the cause must be determined and corrected. In some

cases, a special vent cap may be required.

If the back draft cannot be corrected by normal methods or if a suitable

draft cannot be obtained, additional make up air must be provided to the

room to assure proper venting and combustion.

Note: A negative draft must be maintained in the vent piping.

The barometric draft regulator must be installed in the same room

as the heater, fig. 6. Locate the regulator as close as possible to

the heater and at least 18" (457.2 mm) from a combustible ceiling

or wall. A manually operated damper should not be placed in the

chimney connector.

PROPER VENT CONNECTOR INSTALLATION

FIGURE 6.

CHIMNEY

The oil-red water heater must be connected to a chimney built in

accordance with accepted building code practice or listed factory built type,

Table 5. The exit point of the chimney ue gas must be at least 3' (0.91

M) above the highest point where it passes through the roof of a building.

Also, it must be at least 2' (0.61 M) higher than any portion of a building

within 10' (3.05 M) of the chimney.

MULTIPLE HEATER FLUES

When two or more oil-red water heaters are connected to a single chimney

or vent there shall be sufcient draft available for safe combustion and

removal of combustion products to the outdoors from each heater. Refer

to local codes for connection details.

Only one oil-red water heater should be connected to any one type L

venting system.

A draft regulator shall be provided for each oil-red water heater in a

multiple heater system.

DANGER

INCORRECT INSTALLATION CAN CAUSE IMPROPER OPERATION,

FIRE,

ASPHYXIATION, SERIOUS PERSONAL INJURY OR DEATH. NEVER

OPERATE THIS WATER HEATER UNLESS IT IS PROPERLY VENTED

TO THE OUTDOORS AND HAS ADEQUATE COMBUSTION AIR SUPPLY.
