B. Gas Pressures

C. Gas Connection

Proper input pressures required for optimum appliance per- formance, gas line sizing requirements need to be followed from NFPA51.

WARNING

Fire Risk.

Explosion Hazard.

High pressure will damage valve.

Disconnect gas supply piping BEFORE pressure testing gas line at test pressures above 1/2 psig.

Close the manual shutoff valve BEFORE pressure testing gas line at test pressures equal to or less than 1/2 psig.

NOTE: Have the gas supply line installed in accordance with local building codes, if any. If not, follow ANSI Z223.1. Instal- lation should be done by a qualified installer approved and/or licensed as required by the locality. (In the Commonwealth of Massachusetts, installation must be performed by a licensed plumber or gas fitter.)

NOTE: A listed (and Commonwealth of Massachusetts approved) 1/2 inch (13mm) T-handle manual shut-off valve and flexible gas connector are connected to the 1/2 inch (13mm) control valve inlet.

If substituting for these components, please consult local codes for compliance.

WARNING

Verify inlet pressures.

High pressure may cause overfire condition.

Low pressure may cause explosion.

Install regulator upstream of valve if line pressure is greater than 1/2 psig.

Pressure requirements for appliance are shown in the table below.

PRESSURE

NG

LP

Minimum Inlet Pressure

5 inches w.c.

11 inches w.c.

Maximum Inlet Pressure

10 inches w.c.

13 inches w.c.

Manifold Pressure on “HI”

3.5 inches w.c.

10 inches w.c.

If the pressure is not sufficient, ensure:

1)The piping used is large enough.

2)The supply regulator is adequately adjusted.

3)That the total gas load for the residence does not exceed the amount supplied.

The regulator that attaches directly to the residence inlet or to the propane tank is the supply regulator. It should supply gas at the suggested input pressure listed above. Contact the local gas supplier if the regulator is at an improper pressure.

WARNING

Gas Leak Risk.

Support control when attaching pipe to prevent bending gas line.

NOTE: The gap between the supply piping and gas access hole may be plugged with non-combustible insulation to prevent cold air infiltration.

Leak test all gas line joints and the gas control valve prior to and after starting the appliance.

Before making the gas connection, ensure that the appliance you are installing is designed for the type of gas being supplied. This information can be found on the Ratings Label under the appliance. If the appliance has been converted to propane (LP), the valve cover should have a label stating that the unit has been converted to propane.

Connect the gas line at the 3/8 in. (9.5mm) pipe connector on the valve at the back of appliance. We recommend connecting the appliance with an approved flex gas line. If flex gas lines are not approved in your area, you must connect a hard pipe to the gas hookup.

You must supply a manual shut-off valve in a visible location within 3 feet (914mm) of the appliance.

SAPPHIRE-D-CSB, SAPPHIRE-D-PMH, SAPPHIRE-MBK, SAPPHIRE-D-MBK specifications

The Quadra-Fire Sapphire series of fireplaces, which includes the Sapphire-D-PMH, Sapphire-D-CSB, Sapphire-D-MBK, and Sapphire-MBK models, epitomizes modern heating technology combined with elegant design. These units are meticulously engineered to enhance both efficiency and aesthetics, making them perfect additions to contemporary living spaces.

One of the standout features of the Sapphire series is its advanced combustion technology. The fireplaces utilize a patented Clean Burn technology. This innovation ensures that the combustion process is as efficient as possible, resulting in reduced emissions and maximizing heat output. With lower particulate emissions, these models not only provide warmth but do so in an environmentally conscious manner.

In terms of performance, the Sapphire fireplaces are designed to deliver consistent and radiant heat. With their powerful heating capabilities, they can warm up large areas, making them suitable for homes of various sizes. The efficient design helps to distribute heat evenly throughout a room, eliminating cold spots and ensuring comfort in all corners of your living space.

The design aesthetics of the Sapphire series is equally impressive. The models feature a sleek, modern design complemented by a large viewing area, allowing for an unobstructed view of the mesmerizing flames. The glass is designed to remain clean for longer periods, thanks to the sophisticated airflow management system that directs air over the glass surfaces, reducing soot buildup.

Customization options are another notable characteristic of the Sapphire series. Homeowners can choose from various finishes and styles to match their home’s decor. The units are available in both traditional and contemporary designs, allowing for versatility in different architectural settings.

The Sapphire-D-PMH model is equipped with a programmable thermostat for added convenience and efficiency. This technology allows users to set the desired temperature, ensuring that their space remains comfortable without unnecessary manual adjustments.

On the other hand, the Sapphire-D-CSB model features an innovative fuel management system that optimally uses wood fuel for extended burn times. This means less frequent refueling and more time spent enjoying the warmth and ambiance the fireplace provides.

The Sapphire-D-MBK and Sapphire-MBK models are designed with durability and longevity in mind. Each unit is constructed from high-quality materials that are built to withstand extreme temperatures while maintaining structural integrity over time.

In summary, the Quadra-Fire Sapphire series combines advanced technology, unique design, and high efficiency. With features like Clean Burn technology, customizable options, and smart fuel management systems, the Sapphire fireplaces offer not just heat, but a stylish centerpiece for modern homes.
