The incident happened at around 11pm on Wednesday in the Ballyconnell Road area of Derrylin.
The tanker had been stolen from a nearby property before it was reversed into the front of the building and the cab set alight.
The Fire Service attended the scene and extinguished the blaze before it spread to the building, which was seriously damaged.
Sinn Féin MLA Phil Flanagan condemned those behind the arson attack.
He said: "This is a despicable act and is not representative of the local community.
"Those behind these actions are not acting out of loyalty to the Quinn family and are not furthering any cause.
"The only result of such activity will be employment opportunities being impacted upon and that is a matter of grave concern for the people of the local community."
Former billionaire Sean Quinn, once Ireland's richest man, built a huge business empire before its spectacular collapse in 2011. Since then there have been a number of attacks on properties formerly owned by the Quinn family.
The Quinn Group was recently rebranded as Aventas.
A statement from the Aventas Group said that the company has been subject to a campaign of sabotage, intimidation and vilification.
The firm said that it will face down the misguided minority behind the attacks.
In a statement issued on Thursday night, the PSNI condemned what they described as criminal damage and attempted arson attack.
Police said this was "a reckless action" which could have had serious consequences to people still on the premises or to other members of the public using the main road which was only some meters away.
The statement continued: "While police aimed to minimise any adverse disruption to the local community, those who perpetrated this attack last night had no regard for those working, living or visiting the area in the weeks running up to Christmas."
Police are appealing to anyone who was travelling along the Ballyconnell Road on Wednesday between 10.30pm and 11.30pm and noticed any suspicious activity to contact them.
