CHAPTER 4 - WATER HEATER START-UP
4.1. Filling the Inner (Domestic Water) Tank
• Never use water heater unless inner and
outer tanks are completely filled with water.
• Inner tank must be completely filled and
pressurized before pressurizing outer tank.
1. Close domestic water drain valve.
2. Open domestic water isolation valves for water
heater.
3. Vent air from inner (domestic water) tank by open-
ing nearest hot water faucet. Fill domestic water
tank completely by allowing water to run until
there is a constant flow of water.
4. Close hot water faucet.
4.2. Filling the Outer (Boiler Water) Tank
• Never use water heater unless inner and
outer tanks are completely filled with water.
• Inner tank must be completely filled and
pressurized before pressurizing outer tank.
1. Close boiler water drain valve at boiler water outlet
of water heater.
2. Open water heater’s boiler water isolation valves.
3. Allow air to escape from outer (boiler water) tank by
opening manual air vent, located on top of water
heater.
4. Follow instructions furnished with boiler to fill with
water.
5. When tank is full, and air stops escaping, close the
manual air vent.
6. If antifreeze is used in boiler water, check concen-
tration. Boiler water (including additives) must be
practically non-toxic, having toxicity rating or class
of 1, as listed in Clinical Toxicology of Commercial
Products.
Do not use automotive, ethylene glycol or pe-
troleum-based antifreeze. Do not use any un-
diluted antifreeze. This can cause substantial
property damage, serious injury, or death.
CAUTION
CAUTION
WARNING
HOT WATER CAN SCALD!
Water temperature over 125ºF can cause se-
vere burns instantly or death from scalds.
• Feel water before bathing or showering.
• Consumer Product Safety Commission
and some states recommend tempera-
tures settings of 130ºF or less. Setting ther-
mostat higher than 130ºF will increase risk
of scald injury and cause severe personal
injury or death.
• Water heated to a temperature suitable
for clothes washing, dish washing and
other sanitizing needs will scald and cause
permanent injury.
• Children and elderly, infirm, or physically
handicapped persons are more likely to
be injured by hot water. Never leave them
unattended in or near a bathtub. If anyone
using hot water in the building fits this
description, or if state laws or local codes
require certain water temperatures at hot
water faucets, take special precautions.
– Install an automatic mixing valve at
water heater or at each hot water fau-
cet, bath and shower outlet. Selection
and installation must comply with
valve manufacturer’s recommenda-
tion and instructions.
– Use the lowest practical temperature
setting.
–
Check water temperature after any ad-
justment. You must follow “Adjusting the
Water Heater Thermostat” procedures.
At no time should boiler limit control be set
above 210ºF. This can cause substantial prop-
erty damage, serious injury, or death if ig-
nored.
