Bradford White CombiCor TTW User manual

Residential Energy Saver
Power Vent CombiCor®Direct-Fired
Gas Water Heater System
Features:
Bradford White is ISO registered to the
9001 standard.
■Power vented for positive exhaust during main burner operation—the TTW2
uses a specially designed assembly that blows exhaust gases directly out of the
building, eliminating the need for conventional chimneys or expensive flue
systems.
■Electronic ignition—electronic ignition eliminates the constant burning pilot
used on other water heaters. This device results in savings of pilot gas during
stand-by periods. (115V AC required to heater). Ignition system operates off of 24
volts.
■3" PVC, ABS and CPVC (76mm) vent—the water heater can be vented
horizontally or vertically with 3" (76 mm) PVC, ABS, CPVC for lengths up to 30
feet (9.1 m) with (3) 90° elbows. (45 equivalent feet) (13.7 m).
■4" PVC, ABS and CPVC (102mm) vent—the water heater can be vented
horizontally or vertically with 4" (102mm) PVC, ABS, CPVC for lengths up to 60
feet (18m) with (3) 90° elbows. (75 equivalent feet) (23m).
■Vitraglas®lined tank—Bradford White water heater tanks are protected from the
corrosive effects of hot water by an exclusive ceramic porcelain-like coating. The
Bradford White high silica Vitraglas®lining provides a tough interior surface for
our water heater tanks.
■Anti-scald device—supplied with unit to help prevent injury due to scalding.
■Protective magnesium rod—provides added protection against corrosion for
long trouble-free service.
■Factory installed dielectric waterway fittings—all heaters equipped with
special water heater nipples for longer life.
■2" Non-CFC foam insulation—covers the sides and top of tank to save energy
by retarding loss of heat. Also increases jacket rigidity.
■Heat exchanger – UltraCoil®Heat Transfer System—dielectrically isolated,
double wall type consisting of a highly conductive material with an NSF approved
Polyethylene (PEX) coating. Also, incorporates two monofilament channels
between the walls for leak detection purposes. Leak detection hole is located at
top of unit on both heat exchanger connections.
■Fully automatic controls—fast acting surface-mount thermostat for automatic
temperature control. Built-in energy cut-off switch prevents abnormally high
water temperature for extra safety. Combination gas valve/electronic module has
built-in gas pressure regulation and electronic circuit controls and operates off 24
volts.
■T&P relief valve included.
■Brass drain valve.
■Flue baffle—designed to maximize the amount of heat absorbed in the lower
portion of tank. Reduces air movement in the heater during standby periods to
retard heat loss up the flue.
■Ten year limited warranty on steel tank and heat exchanger—heavy gauge
steel automatically formed, rolled and welded to assure a continuous seam for
glass lining.
■Six year limited warranty on parts.
■Design certified by CSA International (formerly AGA and CGA)
