SECTION 1.
Caring For Your Endurance
Your Endurance will require very little
maintenance. However, as with any fine appliance,
there are certain steps you should take to insure
continuing optimum performance.
1A. General Care
Keep your Endurance area clear and free from
combustible materials, gasoline and other flammable
vapors and liquids.
If you desire, clean the jacket surfaces with a
damp cloth and mild soap. Do not use flammable
cleaning materials.
Keep vent terminal free of obstructions. Do not
pile snow against vent terminal.
1B. Annual Inspection of Flues and Vents
You should visually inspect the vent pipe once a
year. Should any corrosion exist, have the affected
parts replaced.
On horizontally vented units installed with
p/n 2400-009 (Direct Vent Kit) inspect the metal vent
terminal (see Figure 3) on the outside of the building
for corrosion. Replace if necessary.
On all models installed without the Direct Vent
Kit, clean and inspect the condensate collection and
disposal system which is a part of the flue assembly.
1C. Shutting Down the Endurance
The need may arise to shut down your Endurance
(extended stay away from home, for example). If so,
the following steps are required:
1. Switch off main disconnect switch (located on
back of control panel).
2. Close gas shutoff valve above combination gas
control valve (inside unit).
3. Close main manual gas valve.
4. If freezing is anticipated, drain Endurance and
be sure to protect building piping from
freezing, also.
The above steps may require qualified service
personnel.
1D. To Restart Endurance
Should the need arise (power interruption, for
example), you may have to restart your Endurance.
Follow these steps:
1. Depress the reset button on the top of the control
panel for at least one second, and then release.
2. Turn up thermostat to call for heat.
3. In approximately 2 seconds, the blower will
operate and ignition should occur after 35-40
seconds. It may take as long as 2½ minutes.
4. If ignition does not occur, wait 5 minutes and
then repeat steps 1 through 3.
5. If, after three attempts, you still are unable to
achieve ignition, shut down the boiler and call
your service technician.
If drained, follow these steps:
1. Follow “Installation Manual” for proper filling
and purging.
2. Turn on main manual gas valve.
3. Remove front door and turn on gas shutoff valve,
above combination gas control valve.
4. Switch on main disconnect switch, depress on/
off button on front of control panel, and depress
black reset button on top of control panel (pump
and blower will start and igniter will be
energized, after 35 seconds the gas valve will be
energized, and ignition will occur). If ignition
does not occur within 2½ minutes switch “off”
main disconnect switch, wait 5 minutes and
switch “on” again. If after three attempts ignition
does not occur, initiate shutdown procedure and
call for service.
1E. In the Event of Power Failure
The Endurance cannot be operated during an
electrical power outage. If there is an extended power
outage with danger of freezing, then the Endurance
(and all other water systems) should be completely
drained. When draining the unit, turn off gas and turn
off the main power switch. When replacing in service,
refer to start-up instruction for proper filling and
purging.
1F. Full Service Every 3 Years
In addition to the annual visual inspections by
the homeowner, a qualified service agency should
conduct a detailed inspection of all flue product
carrying areas of the boiler and vent system. This
should be done in accordance with the service
instruction in the “Installation and Operating
Instructions Manual” for the Endurance.
Caution
Do not use this boiler if any part has been under
water. Immediately call a qualified service
technician to inspect the boiler and to replace any
part of the control system and any gas control
which has been under water.
WARNING
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 Endurance.
En cas de surchauffe ou si l’admission de gaz ne
peut être coupée, ne pas couper ni débrancher
l’alimentation électrique de la pompe. Fermer plutôt
le robinet d’admission de gaz à l’extérieur de
l’appareil.
