Common Flue Installations

In some areas it is possible to vent more than one gas fireplace into the same flue. You must ensure the flue being shared has the proper capacity to handle both fireplaces. Check installation codes for venting capacity information.

As always it is best to check with the authority having jurisdiction prior to commencement of the installation.

Liner Installation

Insert liner from top of chimney through the damper opening and attach to 3" flue collar (for A125); 4" flue collar (for A132). For best results use three (3) sheet metal screws and a hose clamp.

For natural draft inserts, packing fibreglass insulation around the liner in the damper area will isolate the fire- place cavity from the chimney and prevent drafts and noises during operation.

In case the fireplace opening is only minimum height (17¹⁄₂" for A125) (20" for A132) and access from the front is not possible, remove the flue collar plate - un- screw and slide out from the back of the unit. Now attach the liner to the flue collar, lift up and simply slide flue collar plate back onto the unit top. It is important the plate is completely inserted and the front screw is fastened again in order to line up the flue outlet and the liner properly. (Fig. 10)

If fireplace lintel is wider than 8" (203 mm), the height of the fireplace opening must be 25" (635 mm) to allow for a 90° offset elbow to be installed.

Draft Relief Opening

This insert is equipped with a draft-relief opening which receives its dilution air supply through the opening behind the louvres. These openings must not be obstructed or altered in any way. (Fig. 11)

Gas Fireplace Insert

Test Chimney Draw

A "Chimney Draw" test must be made before the installation is complete.

1.Close all doors and windows in the home and start exhaust fans in the kitchen and bathroom.

2.Light unit and operate for 5 minutes.

3.Hold an ignited match or cigarette in front of the unit. Refer to Figure 11 for the location of the draft hood opening.

4.Check to make sure smoke from the match or cigarette is drawn into the fireplace. If it is not, turn the unit off and check for causes creating the lack of adequate draft.

Vent Safety System

These inserts are equipped with a vent safety shut down switch. This switch is factory installed, wired and tested. Check and make sure the switch and wires are in the proper position. The safety switch is heat activat- ed and wired in series with the pilot system. (Fig. 12)

A132, A125 specifications

CFM Corporation, a renowned leader in the aviation industry, has made significant strides with its advanced jet engines, particularly the CFM56 series, which includes models like the A132 and A125. These engines are propelling the next generation of commercial aviation with their focus on fuel efficiency, reliability, and reduced emissions.

The CFM A132 and A125 engines are specifically designed for narrow-body aircraft, making them ideal for short to medium-haul flights. One of the standout features of the A132 is its exceptional thrust performance, providing operators with a thrust range that ensures versatility in various flight conditions. The A125, while slightly lower in thrust output, boasts impressive fuel efficiency, contributing to lower operational costs for airlines.

Both models utilize advanced materials and manufacturing techniques that enhance durability and performance. CFM incorporates innovative ceramic matrix composites (CMCs) and advanced alloys in their designs. These materials offer increased resistance to high temperatures and reduce overall weight, resulting in improved engine performance and longevity.

A key technology present in both A132 and A125 engines is the 3D-printed components, which enable intricate designs that were previously impossible or too costly to produce. This innovative manufacturing method not only simplifies production but also reduces waste and enhances the engines' overall performance.

Noise reduction technologies are also a priority, as the aviation industry increasingly focuses on minimizing its environmental impact. Both models feature advanced acoustic liners and the latest in fan blade design, significantly decreasing noise levels during operation. This is particularly beneficial for airlines operating flights in and out of urban areas where noise restrictions may apply.

Moreover, CFM's engines are renowned for their reliability, with maintenance intervals designed to extend engine life and reduce downtime. The A132 and A125 benefit from CFM's extensive experience and proactive approach to service, ensuring operators have access to support throughout the engine's lifecycle.

In summary, CFM Corporation's A132 and A125 engines represent a blend of advanced engineering, innovative technologies, and customer-centric design. With their powerful performance, fuel efficiency, and commitment to environmental sustainability, these engines are set to continue shaping the future of aviation. Airlines that invest in these models gain not only superior operational capabilities but also the promise of reliability and cost-effectiveness in an increasingly competitive market.
