Hot Supply from

Hot Supply to Heat Emitter(s)

Return to

Outdoor Furnace

Return from Heat Emitter(s)

Water at 150°F up to 170°F at Thermostatic Valve

(water is partially released to heat emitter(s) and partially bypassed)

(arrow indicates water flow)

Optional Thermostatic Valve - How It Works

Valve shuts off flow to heat emitter(s).

Valve bypasses heat emitter(s).

Valve allows full flow to heat emitter(s).

Valve shuts bypass.

Valve allows partial flow to heat emitter(s).

Valve allows partial bypass.

Note: Top of valve

can be installed to

face either direction.

As shown here or

as shown below.

NOTE

Install a Thermostatic Valve on each set of supply and

return lines in the system. Each Thermostatic Valve

must be installed inside the building to be heated.

NOTE

The proper level of Corrosion Inhibitor Plus™ (p/n

1650) must be maintained (see Owner’s Manual for

more information).

OPTIONAL THERMOSTATIC VALVE - HOW IT WORKS

NOTE: With higher heat loads, it may be necessary to change the water temperature setpoint on the

FireStar controller to be no less than 185˚F.

NOTE: When the thermostatic valve allows a trace flow, enough water will pass through for the

backup indoor heating system to backfeed heat to the outdoor furnace and water lines, protecting

against freezing.
