CAUTION: Should overheating occur or the gas
supply fail to shut off, do not turn off or disconnect
the electrical supply to the pump. Instead, shut off the
gas supply at a location external to the appliance.
Do not use this appliance if any part has been under
water. Immediately call aqualified service technician
to inspect the appliance and to replace any part of
the control system and any gas control that has been
under water.
CONDENSATE DRAIN
This unit produces water as a byproduct of combustion.
Much of this water condenses on the heat exchanger
and in the venting system. Condensate must be drained
from the boiler into a household drain as shown in
Figure 1.
Figure 1 Condensate Piping
3. Do not seal the opening between the condensate
pipe and the condensate drain pipe, Figure 1. In the
event of a blocked drain the opening will allow the
condensate to overflow and prevent the boiler from
flooding.
4. Never have the drain pipe higher than the hole in the
back cabinet, this will flood the boiler.
5. Never allow the drain to freeze or become blocked.
This will cause condensate to fill the combustion
chamber resulting in a no heat condition and damage
to the boiler.
6. NEVER use copper, steel, or galvanized piping in
the construction of the condensate system.
7. When a condensate pump is used or required, select
a pump that is designed for residential furnaces.
BOILER MAINTENANCE
CAUTION: Servicing, inspection and adjustment
must be done by a trained technician in accordance
with all applicable local and national codes.
Improper servicing or adjustment could damage
the boiler!

Note: Check with your municipality, or local gas
company to determine if disposal of combustion
condensate is permitted.
The following are important rules that must be followed
when constructing the condensate system:
1. Connect the condensate trap to the drain using
1/2 in, 13 mm, silicone, rubber, reinforced nylon, or
PEX tubing.
2. Do not use nylon tubing, as it will collapse, blocking
drainage. This could damage the boiler.
The boiler should be cleaned and inspected once a year,
before each heating season. Each month the entire vent
system must be thoroughly inspected for any signs of
blockage, damage or leaks. Immediately replace any
unsound vent system piping. Remove any foreign matter
in or near the vent and air intake terminals.
Examine all flue product carrying areas of the boiler and
it's burner to ensure continued safe operation. Ensure
that there is no deterioration from corrosion or other
means. Any unsound flue gas carrying com-ponent must
be replaced!
Ensure that the condensate removal system is sound
and working properly.
