FAQ
What heater models are compatible with the F237349 assembly?
The assembly fits Mr Heater models MH15T, MH15TS, MH30T, MH30TS, MH45T, as well as SunRite models SRC15T and SRC30T. It replaces part #17349 and is designed to work with any heater that uses a standard thermocouple connection.
How does the tip‑over switch enhance safety?
The tip‑over switch detects when the heater is no longer upright. If the unit tips, the switch interrupts the gas flow, shutting the heater off instantly. This prevents fuel from continuing to burn in an unsafe orientation, reducing fire risk and protecting users.
Can I install the assembly myself, or do I need a professional?
Installation is straightforward and can be completed by most users with basic hand tools. The assembly includes clear instructions, and the design allows for a plug‑and‑play replacement of the existing thermocouple. However, if you are uncomfortable working with gas‑powered equipment, we recommend consulting a qualified technician.
What is covered under the one‑year warranty?
The warranty covers any defects in materials or workmanship that arise under normal use conditions. If the assembly fails due to manufacturing issues, we will provide a replacement at no cost. Warranty claims do not cover damage caused by improper installation, misuse, or external factors such as accidents.
Is the multicolor housing purely aesthetic, or does it serve a functional purpose?
Beyond visual appeal, the multicolor housing helps users quickly identify the part during maintenance, especially in environments where multiple components are present. The distinct colors also aid in inventory management for retailers and service technicians.
