General Clearances

The Novo freestanding models have an additional metal wrap which significantly reduces heat transfer. This means the unit can be installed into tight spaces, can be built-in, and can be positioned close to walls if the building materials are suitable. For further information on material selection refer.

General clearances from combustibles
The clearances in this diagram are minimum clearances. The Novo must not be installed where curtains, furniture, or other combustible materials could come into contact with the fire while it is operating. The 1000 mm clearance is in front of the fire.

The general clearances shown below on the Novo Freestander (with cabinet base) apply to all the Novo freestanding models.

Floor protection
Heat radiating from this fire may over time affect the appearance of some materials used for flooring, such as carpet, vinyl, cork, or timber. We don’t recommend installing the Novo Cube directly on the floor if sensitive or unrated materials are used unless there is some protection placed in front of the appliance, such as a mat.

Flueing options

Every gas fire requires a flue system that will draw effectively and clear flue products safely under all potential wind and climatic conditions. It is the responsibility of the installer to ensure the appliance is provided with an effective flue.

The Novo MUST BE installed with a Rinnai-approved flue system, approved components are shown in this guide.

Minimum flue length
This is required to ensure adequate draw and to prevent spill-back of combustion products, which can cause the safety sensors to shut down the fire.

• Min. vertical length: 3 m
• Min. flue length before any bends or offsets: 900 mm (or one length of flue)

Maximum flue length
The maximum flue length is determined by what the product has been tested, verified, and certified to.

• Max. flue length: 8 m
• Max. number of bends: 2 x 45°, or 2 x 90°

Material selection

The temperature in front of the fire (approximately 200-350 mm x 400 mm wide) can reach up to 40 °C above ambient, which is why material selection is important. For example, vinyl planks are a popular option for flooring, however, vinyl is only rated for ambient temperatures. In this example, it would not be recommended that the fire be installed directly on the floor unless there was some form of floor protection in front of the fire. Some material selection guidelines, depending on the material rating, are shown below.

maximum of 20 °C
A| Overhang| No restriction as long as materials within 400 mm to the side (D) are of the same rating| •       Not suitable if B is under 250 mm

•       No restrictions if B is greater than 1000 mm

•       If B is 300-1000, refer.

B| Clearance above| 50 mm min.| 100 mm min.| 200 mm min
C| Side overhang| No restrictions| No restrictions if D is greater than 400 mm
D| Side clearance| 50 mm min.| 50 mm min.| 100 mm min.
E| In front| No restrictions| 150 mm max.| 100 mm max.
F| Clearance to floor| No restrictions| 150 mm min.| 240 mm min.
G| Hearth depth| No restrictions| 400 mm min. of non- combustible material| 450 mm min. of non- combustible material
H| Directly on floor| No restrictions| Not suitable for heat-sensitive materials
I| Flue clearance| 25 mm min.| 50 mm min.
 | The shaded cells denote measurements A, B, C, and D. These figures are dependent on each other and the type of installation. There is some wiggle room to these dimensions if they follow some specific calculations. These calculations are based on figures obtained during in-house temperature testing.|

Just because a material is rated to higher than 60 °C does not mean it will not deteriorate when exposed to heat cycles. Always refer to the material supplier for suitability. The temperatures given are assuming the fire is operating at a room temperature of no more than 25 °C. Operation in higher ambient temperatures may result in higher surface temperatures. Non- combustible materials should be made of heat-resistant material.

Installation examples

Cube installed on a combustible platform

• Depending on the material, refer table on the previous page. The platform could extend 150 mm or 100 mm maximum in front of the fire. This is dimension E in the table.
• The height of the platform would need to be at least 150 mm or 300 mm. This is dimension F in the table.

Cube installed on a non-combustible floating hearth
The only requirement for non-combustible material is a 50 mm clearance from the back of the fire to the wall.

If the material is rated 50 °C or below (above ambient) then:

• 50 mm clearance from the back of the fire to the wall
• In front, the earth could extend 100 mm or 150 mm maximum, this is dimension E in the table.

Freestander with plinth base installed on a wooden floor
Using the table on the previous page there would be no restrictions except a 50 mm clearance from the back of the fire to the wall. The plinth automatically gives the 240 mm minimum clearance from the bottom of the fire to the wooden flooring—this is dimension F in the table.

Cube installed in an alcove
If all materials are non-combustible then the only restrictions are a 50 mm clearance from the back of the fire to the wall, and that the material above the fire is the same as the material to the side of the fire. The flue requires a 25 mm clearance.

If the material is rated 50 °C or below then the following applies:

• It cannot be installed directly on the floor unless there is some form of protection directly in front of the unit.
• Side clearance needs to be at least 50 mm minimum.
• Side overhang (C) can only be 100 mm max. (D + 50 mm).
• Overhang (A) is B-250 mm. B in this example is 500 mm, so the overhang can be 500-250 mm, (A) can be 250 mm maximum.

Running costs

45 kg LPG gas bottle energy calculation

• 1 kg of LPG gas contains 50.4 MJ of energy
• 1 kW = 3.6 MJ
• This means that a 45 kg LPG bottle has approximately 2268 MJ (45 kg x 50.4 MJ)

Natural Gas: Calculating your running costs

1. Calculate the MJ input of the appliance to kW, for example, 14 MJ/h = 3.89 kW/h
2. Calculate the approximate running cost per hour, for example, $0.1414 x 3.89 kW/h = $0.56/hr

LPG: Calculating your running costs

1. Calculate the cost of gas per MJ/h, for example; $115 ÷ 2268 MJ = $0.051 per MJ/h
2. Calculate the approximate running cost per hour, for example, $0.051 x 15 MJ/h = $0.76/hr

LPG and Natural Gas costs

Natural gas
It’s become a competitive market out there and we’re noticing that plans and pricing are more difficult to access without actually switching providers. Natural Gas costs are based on the latest MBIE1 natural gas residential cost as of 2021, which includes GST and a daily fixed line charge. It doesn’t include any prompt payment discount.

• MBIE residential – 0.1441 cents/kWh

www.mbie.govt.nz/building-and-energy/energy-and-natural-resources/energy- statistics-and-modelling/energy-statistics/energy- prices/

LPG (as at May 2022)
To fill a 45 kg gas bottle we found the below numbers, we have averaged this at $109 and used this number to calculate running costs.

• Frank Energy – $104 Dual Fuel Plan or $120 Single Fuel Plan
• Vector Ongas – $110.46 (range on website $110.46-$180.82)
• Trustpower – $102

The above figures exclude LPG bottle rental.
The cost of LPG and Natural Gas will differ in each area, please check with your local supplier. The cost of the cylinder rental, line charges and other variables are not included in the running costs.

Novo hourly running costs

Novo 45 kg LPG bottle run hours and weekly running costs

Gas input| 45 kg bottle will last (hours)| Weekly running costs ($)
---|---|---
Low| High| LPG| Natural Gas
MJ/h| kW| MJ/h| kW| Low| High| Low| High| Low| High
14| 3.89| 30| 8.33| 162| 76| $23.45| $50.40| $19.62| $42.01

This table is meant as a guide only. Please refer to the notes regarding running cost assumptions and how values have been calculated on the previous page. Always double-check figures based on your use.

The weekly running costs are calculated based on the gas fire, during cooler months, operating two hours in the morning and three hours in the evening—a total of five hours use each day.

Please note

• All Rinnai gas fires require electricity to run—electricity costs have not been factored into the running costs.
• The 45 kg LPG bottle hours do not include running times of other gas appliances in use, for example, a gas water heater or a gas hob.
