IBC EX 850 Quick Reference Installation Guide

EX Series Quick Reference Installation Guide
Boiler Mounting (Section 3.0 of the manual)
Venting (Sections 3.5)
Gas Supply (Section 3.9)
Follow the venng specicaons and informaon for the correct venng
material and venng length provided in the above secons of the
manual.
Ensure that sidewall conguraons have adequate vercal separaon,
and that exhaust plumes are well away from all building air intake vents.
Ensure that all venng material is sloped towards the boiler at
a minimum of ⅝″ per foot or at a slope required by the PP vent
manufacturer, whichever is greater.
Ensure that PPs venng is supported every 36″ (min).
On longer horizontal runs of PVC and CPVC, increase the grade to ⅜″ or
more.
Fully insert the approved venng material into the boiler’s exhaust
outlet, and ghten the clamp to ensure
the venng connecon is locked in
place.
Check that the venng is securely
aached to the exhaust ue of the
boiler by pulling on the venng.
Important: Use appropriate appliance adapters when using PPs
or stainless steel venng.
Condensate Trap (Section 3.6)
1. Fill the trap assembly with water.
2. Aach the trap to the drain elbow.
3. Tighten the union nut.
4. Check for leaks.
For gas delivery to the boiler, we recommend using hard piping
rather than exible piping. If you use exible piping, ensure that
the gas pipe size is appropriate for the maximum BTU input of
the boiler.
Minimum Gas Pressure 4" w.c.
Maximum Gas Pressure 14" w.c.
Size piping for sucient sustained gas delivery at sucient
pressure to the boiler.
Recommended Supply Pressure at Full Load
Natural Gas 7"
Propane 10"
• Ensure that there is a minimum of 6 feet of piping between
the boiler and gas regulators.
• Use a manometer to test that gas delivered to the boiler is
delivered at sucient pressure and that “lock up” does not
exceed the maximum pressure.
• If using a 5 psi to inches vented gas regulator, always oversize
the vent pipe to prevent hunng of the gas regulator when
boilers are ring at lower output levels.
In retrots with exisng copper gas pipes, clean and clear the
gas piping of any debris before connecng to the boiler. Failure
to do so can result in a blocked gas valve and inconsistent
performance.

LWCO Errors
To clear LWCO errors caused by air:
1. Ensure that there is no air trapped in the boiler and
boiler piping.
2. On the touchscreen controller Main Menu, go to
Diagnoscs> Advanced Diagnoscs> Clear System
Errors> Yes> OK.
Ensure that the boiler’s anchor brackets are securely bolted to the
oor.

Important: Before turning o the boiler, make sure it is in
“Standby” mode.
Low Gas Pressure Errors (Section 6.3.5)
Every new install will require reseng the low gas pressure
switch. To do so, press on the red reset buon.
Important: Not applicable for construcon heang. Fouled fans,
burners, and ignitors are not covered under warranty.
