Thermo Products GMC-85, OMC-70 specs

All installations and services must be performed by qualified service personnel.

If possible, install the tubing under the floor. Specific information on piping, fuel pump connections, lift capabilities and tank installations is provided in the fuel pump manufacturer’s instructions.

If the oil tank is located inside the building and the tank capacity is between 10 and 660 gallons, it shall not be located within 5 feet horizontally from any source of heat, or oil- burning appliance. Furthermore, the oil tank shall not block access to utility service meters, switch panels, and shutoff valves.

If an underground tank used, the top of the tank should be below all piping in order to prevent oil discharge through a broken connection. Underwriters Laboratories requirements now stipulate that all 275 gallon and larger tanks have a bottom outlet. This is to prevent the accumulation of condensate, which causes the tank to rust. It is also recommended to use a water trap or additives to prevent condensate accumulation.

If the tank is above the burner, and gravity oil feed to the burner is permitted, a single line system may be used. The line should have a gradual slope downward of approximately 1/2 inch per foot, or more, to a point directly below where it is connected to the pump. Installing the line with a downward slope will help prevent the formation of air pockets in the line.

IMPORTANT: An oil safety valve or a delayed-action solenoid valve is required with all gravity feed oil supply systems.

IMPORTANT: The oil storage tank must be free of water, sludge and scale to prevent excessive wear and possible damage to furnace oil pump and burner nozzle. A fuel oil filter installed in the oil supply line to the burner is required.

OIL FILTER: For all installations, use a low micron, oil filter with the capacity to trap particles 10 microns in diameter, or greater. Filtering the oil supply helps to prevent nozzle clogging. Install the oil filter inside the building between the tank shutoff valve and the burner. The filter cartridge should be replaced at least once a year. The filter body should be thoroughly cleaned before installing a new cartridge.

Thermo Products has built a reputation for delivering top-notch heating and cooling solutions, and the GMC-85 and OMC-70 models are no exception. These high-efficiency gas furnaces are designed to meet the diverse needs of homeowners while prioritizing energy savings and comfort.

The GMC-85 model is known for its impressive efficiency ratings, operating at an AFUE (Annual Fuel Utilization Efficiency) of up to 85%. This means that a significant portion of the fuel consumed is converted into usable heat, making it an economically sensible option for heating your home. Additionally, it features a multi-speed blower motor, which allows for better air circulation and consistent heating throughout the living space. This model also includes a durable heat exchanger crafted from high-quality materials, ensuring longevity and reliability in performance.

On the other hand, the OMC-70 furnace offers a slightly lower AFUE rating of 70%, but it shines in certain areas such as cost-effectiveness and straightforward installation. Its reputation for reliability is bolstered by its rugged design and construction that can withstand the rigors of various climates. The OMC-70 also includes a standard efficiency motor, contributing to reduced energy consumption while delivering appropriate heating requirements for smaller spaces.

Both models utilize advanced technology aimed at improving user convenience and efficiency. Features such as electronic ignition systems enhance reliability by eliminating the need for a pilot light, while also providing a quick and efficient startup process. Furthermore, each unit can be easily integrated with smart thermostats, allowing homeowners to manage their heating needs remotely for optimized performance.

Noise reduction is another characteristic that sets these models apart. Both the GMC-85 and OMC-70 employ sound-dampening technologies to ensure quieter operation, providing a peaceful environment for families.
