Resideo TK300-30A-1FM Boiler Trim Kit
The Resideo TK300-30A-1FM Boiler Trim Kit is a comprehensive solution for field technicians performing boiler change-outs or new hydronic installations. This professional-grade boiler trim kit features a 4.4-gallon TK300-30 expansion tank with a durable Butyl/EPDM diaphragm, engineered to effectively manage hydronic system pressure in closed heating loops. The assembly includes a 1-inch AP400 cast iron air purger and an FV180 Goldtop air vent for continuous air elimination, preventing common issues like system noise and heat transfer inefficiency. Additionally, the kit integrates the FM911 boiler fill valve with a backflow preventer, providing reliable pressure reduction and protection against back-siphonage.
- Streamlined Installation: Simplifies procurement and field assembly by combining the expansion tank, air purger, and fill valve in one package.
- Advanced Air Management: The 1-inch air purger and universal air vent work in tandem to strip microbubbles and free air from the circulating water.
- Serviceability: Includes SCV-0125 and SCV-050 service check valves, allowing for the replacement of the tank or vent without draining the entire system.
- Robust Construction: The expansion tank utilizes a deep-drawn steel shell and a high-integrity diaphragm that outperforms natural rubber in thermal stability.
Common Questions & Answers
Does this kit include a backflow preventer?
Yes, the Resideo TK300-30A-1FM includes the FM911 combination boiler fill valve, which features an integrated dual-check backflow preventer.
What is the pre-charge pressure of the expansion tank?
The tank is factory pre-charged to 12 PSIG, which is the standard setting for most residential hydronic systems.
Can the tank be serviced without a full system drain?
Absolutely. The included service check valves are specifically designed to isolate the components, which saves significant time during maintenance or future swaps.
