Okay, let's break down this situation with your customer's Hardie outdoor wood stove and the GFCI tripping issue.

Understanding the Problem Moisture and GFCI

Moisture is a very common cause of GFCI trips. Water creates a path for current to leak to ground, which is exactly what a GFCI is designed to detect.

Age

After 13 years, components can degrade. The receptacle itself, the pump, or the fan could be contributing to the problem due to insulation breakdown or internal faults.

GFCI Function

The GFCI is there to protect users from electric shock hazards that can occur if there's a fault in the wiring of the pump or fan.

Analyzing the situation of eliminating the GFCI Electrical Codes

If the wood stove is considered to be used in wet location, then the National Electrical Code (NEC) requires ground-fault circuit-interrupter (GFCI) protection for receptacles in wet locations and/or locations that are readily accessible.

Manufacturer Requirements

Eliminating the GFCI receptacle, might create a liability for your customer if anything happens to the stove.

Safety

GFCI protection is required for additional protection.

Troubleshooting Steps (Before Direct Wiring)

Before considering direct wiring and potentially creating a safety or code compliance issue, I'd recommend these steps:1. Dry It Out Thoroughly

Completely disconnect the stove from power. Open the back cover and use a hairdryer (on a low, cool setting) or a fan to thoroughly dry out the area around the receptacle and any visible wiring. Give it a good amount of time to ensure all moisture is gone. Consider using a moisture absorbent product (like DampRid) in the enclosure for a few days.2.

Inspect the Receptacle

Visually inspect the GFCI receptacle itself. Look for cracks, corrosion, or any signs of damage. Test the GFCI receptacle with a GFCI tester (available at any hardware store) before plugging anything into it. Does it trip reliably when you press the test button? If not, the receptacle itself might be faulty and need replacement.3.

Inspect Wiring

Carefully examine the wiring to the pump and fan. Look for: Cracked or brittle insulation Exposed wires Loose connections Corrosion4.

Isolate the Problem

Unplug both the pump and the fan from the GFCI receptacle. Reset the GFCI. Plug in only the pump. Does it trip? If so, the pump is likely the culprit. If the pump doesn't trip, unplug it and plug in only the fan. Does it trip? If neither trips individually, plug them both in. Does it trip now? This could indicate a cumulative leakage issue.5.

Replace Suspect Components

If the GFCI receptacle is faulty, replace it with a new, outdoor-rated GFCI receptacle. If the pump or fan is tripping the GFCI, replacing the faulty component is the safest solution.

Regarding Direct Wiring (Eliminating the GFCI Receptacle)Important Considerations



Code Compliance

You must adhere to all applicable electrical codes (NEC and any local codes).

Safety

Ensure the wiring is done correctly to prevent electrical shock hazards.

Grounding

Proper grounding is critical for safety, especially in damp environments.

Warranty

Direct wiring may void any warranty on the stove or its components.

If you're considering direct wiring and all troubleshooting steps have failed, it must be done correctly


Use Appropriate Wiring

Use wiring that is rated for outdoor use and wet locations (e.g., THWN or UF cable). The wire gauge must be appropriate for the current draw of the pump and fan.2.

Proper Connections

Use appropriately sized wire connectors that are rated for outdoor use to make the connections inside the junction box.3.

Grounding

Connect the ground wire from the pump and fan to the grounding conductor in the junction box.4.

Strain Relief

Use strain relief fittings where the wiring enters the junction box to prevent stress on the wires and connections.5.

GFCI Protection

You can install a GFCI breaker on the circuit that feeds the wood stove, this will provide the same level of protection as the GFCI receptacle.

Recommendation1. Thorough Troubleshooting

Focus on identifying the source of the moisture and the faulty component (receptacle, pump, or fan).2.

Replace Faulty Components

Replacing the faulty component is the best solution.3.

GFCI Protection

Maintain GFCI protection. If the receptacle is problematic, consider a GFCI breaker instead.4.

Professional Opinion

This is a good place to defer to a licensed electrician, for your customer. The electrician will be able to properly diagnose the issue and give recommendations based on local building codes.
