9.10 GAS VALVE VOLTAGE
This appliance uses a transformer to supply a 24 volt
signal to the Honeywell SOLA. The voltage on the
secondary side should be 24 to 28VAC when measured
with a voltmeter. A secondary voltage of 21VAC or less
supplied to 24VAC components may cause operational
problems.
9.11 COMBUSTIBLE MATERIALS
CAUTION
Keep appliance clear from combustible materials; do not
store GASOLINE and other flammable vapors and liquids
in the proximity of the appliance.
9.12 FREEZE PROTECTION FOR INDOOR &
OUTDOOR INSTALLATIONS
Installations are not recommended in areas where the
danger of freezing exists. Proper freeze protection must be
provided for appliances installed outdoors, in unheated
mechanical rooms or where temperatures may drop to the
freezing point or lower. If freeze protection is not provided
for the system, a low ambient temperature alarm is
recommended for the mechanical room. Damage to the
appliance by freezing is non-warrantable.
•
Location - Heating boilers, hot water supply boilers or
water heaters must be located in a room having a
temperature of at least 40ºF (5ºC).
•
Caution - A mechanical room operating under a
negative pressure may experience a downdraft in the
flue of an appliance that is not firing. The cold outside
air may be pulled down the flue and causing a frozen
heat exchanger. This condition must be corrected to
provide adequate freeze protection.
•
Freeze protection for the appliance using an indirect
coil can be provided by using hydronic system
antifreeze. Follow the manufacturer’s instructions. DO
NOT use undiluted or automotive type antifreeze.
•
Shut-down and draining - If for any reason, the unit is
to be shut off in a space where danger of freezing
exists, the following precautionary measures must be
taken:
o
Shut off gas supply.
o
Shut off water supply.
o
Shut off electrical supply.
o
Drain the main exchanger and the brazed plate
heat exchanger, if supplied, completely.
o
Ensure that the pump and connecting piping are
fully drained.
9.13 FREEZE PROTECTION FOR A HEATING
BOILER SYSTEM (Optional)
•
Use only properly diluted inhibited glycol antifreeze
designed for hydronic systems. Camus recommends
using a 30/70 mixture of glycol antifreeze to water. DO
NOT exceed a mixture of 50/50.
•
Follow the instructions from the antifreeze
manufacturer. Quantity of antifreeze required is based
on total system volume including expansion tank
volume.
•
Antifreeze is denser than water and changes the
viscosity of the system. The addition of antifreeze
will decrease heat transfer and increase frictional
loss in the boiler and related piping.
Where
antifreeze has been used, to maintain the
temperature rise across the appliance confirm that
the recommended GPM for pure water has been
increased by 15% and the head loss by 20%.
•
Local codes require a back flow preventer or actual
disconnect from city water supply when antifreeze is
added to the system.
•
Always follow the chemical manufacturer’s directions
when filling or topping-up the system with water mixed
with antifreeze. This will prevent any possible reaction
of the water with antifreeze which can create sludge.
