8-1-3. Combustion Control

(1) Combustion

Combustion air is supplied into the burner for 20 seconds prior to ignition. The variable speed combustion air blower motor speed is sensed and controlled. After this pre-purge is competed, spark ignition is provided at the burner. Burner condition is monitored continuously during the burning period.

(2) Safety Controls

Following safety devices function to control the gas solenoid valve to shut off

Flame Detection Circuit: Stops gas flow with flame sensor circuit

Bimetal Thermostat:

Stops gas flow with bimetal thermostat at 221°F (105°C)

Thermal Fuse:

Stops gas flow with thermal fuse at 302°F (150°C) — replaceable fuse

Fuse-Control Circuit:

Protected by internal 3A and 5A device

KGS1411, CG1411 specifications

Sanyo KGS1411 and CG1411 are notable solar panel models from Sanyo, a brand recognized for its innovation in photovoltaic technology. These models are particularly designed to deliver high efficiency and reliable performance for residential and commercial solar energy applications.

One of the standout features of the Sanyo KGS1411 is its use of HIT (Heterojunction with Intrinsic Thin layer) technology. This cutting-edge technology combines crystalline and thin-film solar cells, resulting in a unique structure that maximizes light absorption. The HIT technology results in higher conversion efficiency compared to traditional solar panels. The KGS1411 can achieve efficiencies of up to 20.4%, making it an excellent choice for those looking to maximize energy output from limited rooftop space.

The CG1411 model complements the KGS1411 by offering enhanced performance in low-light conditions. It is particularly effective in urban settings or regions with frequent overcast weather. This model also employs advanced cell design that improves performance during high temperatures, avoiding the efficiency loss typical in conventional solar panels.

Another significant characteristic of both models is their durable construction. Sanyo panels are designed to withstand severe weather conditions, including strong winds and heavy snow loads. This robustness is complemented by an extended warranty period, giving users peace of mind about their investment.

In terms of aesthetics, both the KGS1411 and CG1411 feature a sleek, all-black design, allowing them to blend seamlessly with various roofing materials. This visual appeal makes them an attractive option for homeowners who prioritize the appearance of their solar energy systems.
