Weil McLain GV Boiler Pressure Switch lockout Q&A

Weil-McLain GV boiler recall notice cited & discussed at InspectApedia.comCondensate in pressure switch line locks out my Weil McLain GV4 Boiler

I am getting a few drops of condensate in the line to the pressure switch on my GV4 Weil McLain boiler.

It is enough that the flow switch will not satisfy for a successful start.

Drain the hose and it is okay for several starts.

After several cycles condensed appears again and locks out the system. Air flow is clean and dry. Could burner assembly need cleaning or replaced? - On 2019-02-12 by Tom

by (mod) - Weil McLain GV4 Boiler Condensate Troubleshooting & Safety Warnings

Apologies Tom an authoritative reply is beyond my expertise. With that caveat I will offer a few comments:

First: Watch out: see this Weil McLain Boiler CO Leak Hazard & RECALL  Information - check your gas valve to see if this important safety recall pertains to you.

Otherwise: I I'd check first to be sure that condensate is being properly routed and the drain is not clogged, kinked, improperly-sloped. I'd look for clots of dust getting into the line, which might indeed point back to a need for cleaning /service.

Specific and key to the Weil McLain gV4 boiler is a bypass circulator that you want checked. If you don't have the manual for your boiler you can obtain one from WeilMcLain at www.weil-mclain.com/sites/default/files/field-file/gv-series-4-manual_1.pdf

or at WEIL McLAIN GV4 BOILER MANUAL [PDF]

Here is an excerpt:

Bypass circulator

The GCM operates the bypass circulator to mix hot water from the boiler outlet with colder return water from the system as needed to prevent condensation of flue gases in the boiler.

When the water returning to the boiler is below 140 °F, the GCM regulates the bypass circulator and system circulator flow rates to raise the return water temperature up to 140 °F before it enters the boiler sections.

By balancing these flow rates, the GCM can protect against condensation even if return water is as low as 60 °F. Pump must remain on boiler — do not remove.

Watch out: there are a lot of other detail about venting the GV4 and about proper handling of condensate including a whole section beginning on p. 12 in the manual.

A mistake coiuld make the boiler unsafe and even risk fatal carbon monoxide poisoning.

Vent system

Watch out: The GV boiler requires a special vent system, designed for pressurized venting with likelihood of condensation in the vent.

This is referred to as ANSI Z21 Class IV, Condensing. You may use any of the vent systems covered by the GV venting supplements included in the instruction manual envelope.

The GV vent starter tee is a special item designed only for the GV boiler, available from each vendor.

Do not attempt to connect the vent to the GV boiler with any other means. DO NOT mix components from different systems.

The vent system could fail, causing leakage of flue products into the living space, causing severe personal injury or death.  

The company states

This manual must only be used by a qualified heating installer/ service technician. Failure to comply could result in severe personal injury, death or substantial property damage.

Non-Condensing Weil McLain GV4 series 2 natural gas boiler is condensing all the time

Non-Condensing Weil McLain GV4 series 2 is condensing all the time.

No matter what the return water temperature is. Sometimes you can see water vapor come from the condensate drain along with the dripping water.

Can you please shed a little information as to what's causing this? (Jan 15, 2016) Alan said:

Reply:

Improper combustion air adjustment or inadequate combustion air can cause condensation as can a boiler leak.

Watch out: inadequate combustion air supply produces not just water but fatal carbon monoxide - see COMBUSTION AIR REQUIREMENTS
