A genuine OEM flue kit for upright/refrigerator models. Designed to upgrade existing fridge installations to an “independent flue” setup . which allows the exhaust system (flue) to be separate from the main vent frame . improving ventilation, safety, and performance.

OEM Part Number: 636974WH / 700-03724

Kit Contains:

• Direct Vent Cap
• T Cap Assembly
• Outside vent cover white

Compatability:

Suitable for all  Thetford fridge models where a flue kit can be installed (“upright”, “absorption”, or equivalent models)

Especially useful where current venting is sealed or sub-optimal, or if you want a dedicated exhaust path (independent flue) rather than shared vent grills

Frequently Asked Questions 

Q: What is an independent flue? Why would I need this kit?
An independent flue provides a dedicated exhaust pathway for your fridge’s gas burner or venting system. If your fridge’s existing ventilation is shared, restricted, or inefficient, installing this kit improves safety (vents exhaust gases correctly), helps cooling performance, and reduces heat build-up around the back of the fridge.

Q: Will this kit fit my fridge model / installation?
Check that your fridge allows for flue installation. Many Thetford upright/absorption models are compatible.

Q: Does this come in other colours?
This specific part is the white cover version.

Q: What’s in the “Direct Vent Cap” & the “T-Cap Assembly”?

• Direct Vent Cap is the external outlet where exhaust gases exit.

• T-Cap Assembly fits on top of the flue pipe internally / at wall-exit point to aid airflow and prevent ingress of rain, animals, or debris.

Q: Do I need to replace my entire vent frame to use this?
Not always. This kit works with many existing vent frames, provided there's provision for the flue exit. Sometimes minor modifications (cut-out or routing of flue pipe) may be needed. Ensure installation follows Thetford’s guidelines to avoid leaks or safety issues.
