Dayton Installation, Operation, Maintenance and Parts Manual

Dayton Patio Heaters

1RVT7 and 1RVT8

Sequence of Operation:

Starting Circuit:

When voltage is applied to L1 and L2, a circuit is

completed from L1 via the blower motor to L2. The

blower fan is mounted in the control box and rated to

supply sufﬁcient air for combustion. Air pressure

generated by the blower will cause the normally open

pressure switch to close. Another circuit is completed

from L1 to the spark ignition module and back to L2.

After a seven (7) second pre-purge, the spark electrode

and gas valve are energized simultaneously. The trial for

ignition is ﬁfteen seconds.

Running Circuit:

After ignition, the ﬂame rod monitors the ﬂame. As long

as a ﬂame is present, the valve is held open. If the ﬂame

is lost, the control acts to close the valve within one

second, and a new trial sequence identical to that at

start-up is initiated. If proof of ﬂame is not established

within the 15 second trial for ignition, the unit will retry

two additional times before entering lockout mode. If

lockout occurs, the control can be reset by brieﬂy

interrupting the power source.

Operation

Important! Before operating the heater, conduct

the following safety procedures:

• Check for any possible gas leaks.

• Alert all persons about the hazards of high surface

temperature and to keep a safe distance away in

order to avoid burns and possible clothing ignition.

• Provide supervision when young children are in the

area of the heater.

• Check to make sure clothing isn’t hung from the

heater and that ﬂammable materials are not placed

on or near the heater.

• Check that all guards or protective devices are in place

and secure.

• Check the hose assembly for excessive abrasion, wear

or damage. If necessary replace.

• Check control compartment, burners and circulating

air passages for debris. If necessary, clean the debris.

WARNING

Improper operation of

the heater may result in

explosion, ﬁre, shock and

carbon monoxide

poisoning. Follow all

guidelines and warnings in this manual and national,

state, provincial and local codes. Always conduct safety

checks before operating the heater. Do not operate the

heater in unsafe conditions.
